In simple terms, an EGR valve (Exhaust Gas Recirculation valve) allows small, but metered quantities of exhaust gas to be recirculated into the engine’s combustion chambers in order to limit the formation of harmful combustion products, the most notable of … Continued
In order for the internal combustion engine in your vehicle to run, it needs to be supplied with a constant influx of fuel. This requires fuel to be transported from the fuel tank to either the fuel injectors or carburetors, … Continued
These days, pretty much every fuel injected vehicle has an electric valve that controls the engine’s idle quality and idle speed. Specifically, the idle control valve (ICV), which is also sometimes called the idle air control actuator, prevents the engine … Continued
Motor mounts can be thought of as shock absorbers for your engine, and as such, motor mounts are critical components for the reduction of noise and vibration in passenger vehicles. Motor mounts can be designed with different priorities in mind. … Continued
An oil pump on a modern engine needs to be in perfect working condition if an engine is to be lubricated properly. Unfortunately, oil pumps also sometimes wear out, and engine failure caused by inadequate lubrication usually follows soon after. … Continued
Throttle position sensors are unique among engine sensors, in the sense that these are the only sensors that directly “translate” driver inputs into changes in the vehicle’s speed. As such, throttle position sensors play a critical role in how well … Continued
As any Boy Scout will tell you, making fire requires three main ingredients. These are air, fuel, and heat. This principle remains true when it comes to creating fire in your engine as part of the combustion cycle. The air … Continued
Perhaps one of the most important gaskets in your entire engine is that which sits between the cylinder head and engine block. This particular gasket is subject to extreme heat, extreme pressures, and comes into contact with fuel, engine oil, … Continued
When it comes to engine heat, balance is key. If you run too hot, your engine overheats causing a catastrophic and very expensive failure. On the flip side, if you run too cold, you increase component wear and significantly decrease … Continued
In the USA, the vast majority of vehicles today are produced with automatic transmissions. Elsewhere, such as Europe and Asia, manual transmissions are more popular, but their availability has slowly declined as they make way for increasingly popular automatic transmissions. … Continued
