Engine Breakthrough

Infiniti QX50

Infiniti is set to release a variable compression four-stroke petrol engine, plus a high-performance “S” line to sit atop all new models.

The upcoming QX50 crossover SUV will be deliver the brand a technical breakthrough, becoming the first car in the world with variable-compression engine technology, the technology which could bring about the death of diesel engines in passenger cars.

To be based around an all-new four-cylinder engine, the variable-compression system is claimed by Infiniti to deliver V6 power with four-cylinder diesel fuel economy.It is said by Infiniti to achieve this by changing the engine’s compression ratio depending on the power demand from the driver.

The new engine also underscores Infiniti’s new family of S models, which will be the Japanese premium brand’s high-performance family and the naming of which is bound to have Audi (which already has S versions of the A3, the A4, the A6, the A8 and the A7, along with its Q3, Q5 and Q7 SUVs) fuming.

“You will find there’s a little red S … And you’ll find that going forward on all our performance vehicles given they have the right engine capacity and performance,” Infiniti boss Roland Krueger stated.

Sensors detect the car's driving condition and use the inputs to instantly select the most suitable compression ratio. The displacement of the engine changes and the compression ratio varies between 8:1 for high performance and 14:1 for high efficiency.

"The ingenuity of VC-T engine technology lies in its ability to transform itself and seamlessly raise or lower the height the pistons reach," the company said.

Compression ratio is the measure of how much the air-fuel mixture is reduced in the engine's cylinders before being ignited to produce power.

The variable compression engine paves the way for lower emissions and fuel economy gains. Infiniti is far from the first carmaker to try to use variable compression, with Porsche, Volvo, PSA (Peugeot-Citroen) and Renault all pushing ahead with research, viewing it as a bridging technology between internal combustion engines and electric cars.

The concept is effectively to change the swept volume of the engine’s cylinders at top-dead center, delivering the best of both worlds for performance and fuel consumption. It’s also far from new, with British internal-combustion engineering legend Sir Harry Ricardo inventing it in the 1920s.

Technology of the day ruled out mass production, but Ricardo’s invention led to his equally pioneering work in fuel quality, which delivered us today’s octane rating system.

Saab’s bankruptcy stopped it from delivering on the supercharged variable-compression four-cylinder petrol motor it debuted at the Geneva Motor Show in 2000. Very much a last addition to Saab’s long list of quirky engineering innovations, its engine split the block into two halves, with what was effectively a hinge in the middle lifting one side of the block up to four degrees higher than the other.

There are other ideas for achieving the same result, though. Yamaha has worked with two-stroke variable-compression motors since the late 1990, while Lotus’ single-cylinder Omnivore concept used a movable puck at the top of the combustion chamber, Orbital fuel injection and a two-stroke cycle. Its development effectively stopped during the Dany Bahar era.

Peugeot’s has a concept dubbed MCE-5, which adjusts the connecting rod’s length via a system that looks fearfully complex, while Dutch engineering outfit Gomecsys has a system it says bolts on to existing crankshafts.

One of the more promising and imaginative ways comes from Finland’s Waulis Motors, with the crankshaft attached to an eccentric wheel, which is itself attached to a guidance wheel.

But Infiniti is staying quiet on whether it’s developing its own system or working with a concept it has bought in from outside.

If not fixed promptly, the problem could get worse so it's important to have your car checked out as soon as possible when you see the check engine light. Oil Pressure Warning Light When the flickers on, it's time to take action and ensure your engine stays running smoothly. The oil filter change should be checked first and if it's clogged or dirty, then it should be replaced with a new one. Next, you'll want to check the dipstick reading of your engine oil. If the oil level is low, you might need to add some more engine oil or even consider using some specialized oil additives. Lastly, if there are any signs of leaks under the car then you will need to have this fixed as soon as possible because this could be causing your vehicle’s loss of pressure in its engine. What can happen if your oil pressure warning lights turn on? It’s important that you take action when the warning lights appear on your dashboard as ignoring them can cause further damage down the line. If any part of your engine fails due to low levels of oil pressure or lack of maintenance then this can result in costly repairs for parts such as pistons, crankshafts and bearings which can end up costing hundreds or even thousands depending on how severe the issue is. How to prevent your oil pressure warning light from turning out? Taking preventative measures by having regular checks done and ensuring all parts are working properly will help keep everything running efficiently without major issues arising. Regularly checking fluid levels like coolant, brake fluid, and especially motor oil are essential steps in maintaining a healthy vehicle so don't forget to check yours periodically! Keep an eye out for unusual noises coming from your car too, such as knocking sounds which may indicate something more serious than just an empty reservoir - get these looked at straight away because they could be indicative of bigger problems down the road. Engine Temperature Warning Light Stay ahead of the game and take care of your car by keeping an eye out for when that temperature warning light flickers on. It could be signaling something more serious than just a hot engine. The engine temperature warning light indicates there's an issue with the engine's ability to stay at its optimal temperature. Usually due to a lack of coolant or low coolant levels in the radiator. This can also be caused by a faulty sensor in the system or damage to one of the radiator hoses. What to do if you temperature warning lights turn on? It's important to act quickly if you see this warning light. If left unchecked, it can lead to major issues like internal engine damage from overheating. If you suspect any kind of issue with your vehicle's cooling system, have it checked out as soon as possible by a professional mechanic. Low coolant levels need topping up and any damaged parts must be replaced before continuing driving. Not only will this help keep your engine running smoothly, but it will also save you money in costly repairs down the road. Monitoring your engine's temperature is essential for keeping it running efficiently and safely. So make sure you pay attention when that temperature warning light comes on! ABS Light Pay attention to the ABS light on your dashboard - it's there to ensure your safety on the road. The ABS ( Anti-lock Braking System) is an important part of a vehicle's functionality, as it helps prevent wheels from locking up during sudden stops or when encountering slippery surfaces. Not only does this improve braking performance and stability, but it also helps you maintain control of your car in such situations. To keep the system running properly, regular maintenance and diagnostics are required. What to do if you ABS warning light stays illuminated? If you see the ABS light illuminated on your dashboard, this indicates that there may be an issue with the system's performance or functionality and should be checked by a professional mechanic.

If you're unsure about how to evaluate or repair any issues yourself, make sure that you consult a qualified technician so they can help restore proper functioning and get you safely back on the road again. Traction Control Light Be aware of the traction control light on your car's dashboard - it's there to help ensure a safe ride. The traction control system, or TCS for short, is designed to monitor and adjust braking power when needed. When the traction control light illuminates, it typically means that one of the wheels is slipping due to low tire pressure or an issue with the brake system. This can be especially dangerous in wet weather or during winter driving when roads are slick or have icy patches. Do my tires impact the performance of my Traction Control System? It’s important to take care of your car by making sure tires are rotated regularly and brakes are inspected regularly so you don’t run into issues while out on the road. In addition to monitoring wheel slip, TCS also helps improve vehicle stability by using sensors that measure lateral acceleration, engine torque, yaw rate and other factors related to your car’s performance on the road. In certain driving conditions such as rain or snow, TCS will apply additional braking power automatically based on data collected from these sensors in order to keep you safe from skidding and sliding off the road. Should You Get Your Traction Control System Inspected? While this feature can provide additional confidence while driving in hazardous conditions, it is important not forget about regular maintenance such as tire rotation and brake inspection so that you can be prepared for any situation while out on the road. It pays to be aware of how your car works and what indicators like the traction control light mean; doing so will help you stay safe no matter what kind of weather comes your way! Tire Pressure Monitoring System Light You'll want to be prepared for any situation while out on the road, which is why it's important to familiarize yourself with your car's tire pressure monitor light. Your tire pressure warning light can indicate a serious loss in air pressure throughout your tires. The tire pressure warning light typically appears as an exclamation point inside a horseshoe-shaped icon located on your dashboard. It indicates that one or more of your tires may have low air pressure. This could lead to unsafe driving conditions and should be addressed immediately. How to test your tire pressure monitoring system? To ensure proper inflation of your car tires, you should pay attention to the type of tires you have, the tread depth, and when they need rotation and alignment. Choosing the right type of tire is essential for good performance; different cars require different types of tires depending on their size and weight load capacity. Tread depth can also affect performance; too much tread will cause difficulty in steering while too little can cause poor traction in wet weather conditions. Finally, having regular tire rotations and wheel alignments will help prevent uneven wear which can lead to excessive wear on some parts of the tire before others are worn down. Keeping up with all these factors helps maintain safe driving conditions so that if you ever find yourself in a situation where your car’s tire pressure monitor light goes off, you can be sure that it is nothing serious or dangerous! Battery Warning Light If you're ever out on the road and notice a battery-shaped icon appear on your dashboard, it could mean that there's an issue with your car's battery and you should take action quickly. This warning light is typically accompanied by other symptoms such as dim headlights or odd noises from the engine, indicating that something may be wrong. How To Inspect Your Car Battery? If this happens, the first step should be to check the Battery Maintenance of your car to make sure it's up-to-date. This includes ensuring all terminals are connected correctly, making sure the electrolyte levels are correct and checking for corrosion or damage to any of the cables. The next step is to perform a Jump Starting test using jumper cables connected to another vehicle with a good battery. If this doesn't work, then it could indicate that there is an issue with either your car's Battery Voltage or the Alternator which needs further inspection. What To Do if Your Alternator is Broken? To determine whether or not one of these components has failed, a professional technician should check both using specialized testing equipment such as multimeters and oscilloscopes. If you find yourself in need of replacing either part then you can expect that they will need replacements along with any associated parts such as pulleys and belts that connect them to other components in your vehicle’s powertrain system. In some cases however, if only one component has failed then it may be possible just replace it alone without having to buy new additional parts - though this decision should always be made after consulting an expert who can advise on what is best for your particular situation. Airbag Warning Light The sight of an airbag-shaped symbol on your car's dashboard can be a cause for alarm, signaling an issue with the vehicle's airbags that needs to be addressed right away. Airbag maintenance is important in ensuring their safety and effectiveness; faults or installation errors can cause the system to malfunction leading to potentially serious harm.

To reduce this risk, it's essential to make sure your car's airbags are inspected and tested regularly by a certified professional who has experience dealing with these kinds of systems. Just like in high-stakes games such as rainbow princess, where precision and timing can mean the difference between a big win and a missed opportunity, staying proactive with vehicle maintenance can safeguard you from costly or dangerous outcomes. Taking steps like this can help you stay safe on the roads while reducing your chances of being injured by an unexpected malfunction in your vehicle's airbag system. Cruise Control Light It's important to be aware of your cruise control light and what it indicates, so you can stay safe on the roads. Cruise control technology has evolved quite a bit in recent years, offering features such as: Cruise Control Activation: Automatically activating when driving above a certain speed. Manual activation for more precise control over speed. Cruise Control Maintenance: Maintaining a steady speed even when facing hills or inclines. Adjusting speeds according to the flow of traffic. Cruise control safety is also improved with the addition of features like adaptive cruise control which helps maintain a safe distance between vehicles and lane departure warnings that alert drivers if their vehicle drifts from its path. All these features provide benefits to drivers such as increasing fuel efficiency, reducing driver fatigue, and providing greater convenience while on the road. Should you get your cruise control system inspected? With all these advantages comes responsibility; always check that your cruise control system is working properly and familiarize yourself with any safety protocols associated with your particular car model before using it. Doing this will help ensure you have an enjoyable and safe experience while using cruise control technology. Seatbelt Warning Light Fasten your seatbelt, you don't want the seatbelt warning light to come on! The seatbelt warning light is a safety measure designed to increase awareness of proper seatbelt installation and use. It's essential that you take the time to ensure your seatbelts are properly installed in your vehicle, as it can be the difference between serious injury or even death if involved in an accident. Seatbelt laws vary by state and country, so it’s important to familiarize yourself with local regulations, and make sure everyone in the vehicle is wearing their seatbelts correctly at all times. Why does the seatbelt warning light turn on? The purpose of the seatbelt warning light is twofold: To remind drivers and passengers of the importance of wearing a safety belt. To alert drivers when a passenger does not have their belt fastened. This reminder gives people an opportunity to double-check that everyone in the car has their belts securely fastened before starting off on any journey - whether long distance or short trips around town. When this reminder system fails for any reason, including loose connections or dead batteries, it’s important for drivers to manually check every occupant’s safety before driving away from any location. How important is it to wear your seatbelt? It's no secret that buckling up saves lives - according to some reports, more than half of occupants involved in fatal crashes weren't wearing a safety belt at the time. Wearing a proper fitting circuit ensures optimal protection during impacts; however many people forget about this rule altogether and put themselves at risk without even realizing it. Letting your friends know about this basic rule may help reduce fatalities due to lack of safety precautions while riding in vehicles. Always remember: buckle up for safety! Brake System Warning Light When your brake warning light turns on, normally this is a sign that your parking brake is engaged. However, it can also be a sign that there is an with your brakes and it's time for an inspection. Sometimes it can also be caused by an issue with the anti lock braking system. Because of the many reasons why your brake warning light can turn on, it's important to have a certified professional diagnose the issue, nothing is more dangerous than misdiagnosing a brake issue.
