A flywheel is a round-shaped mechanical device that connects to the crankshaft generates energy from rotation and then stores that energy for later use. In situations where engine torque is intermittent, the flywheel supplements it with its own stored rotational energy. You will find flywheels in cars with manual transmissions and not in automatic…
The powertrain control module (PCM) is a sophisticated piece of machinery. It receives data from a series of sensors. The engine control module (ECM) and transmission control module (TCM) are examples of systems that the PCM controls. Surprisingly, the PCM also analyzes the data it collects. Use that information to control the ignition system,…
The engine control unit (ECU), also called the engine control module (ECM), is an electronic module that controls the operation of the engine. This is done through a series of electronic components and sensors that compute the data back to the engine. Based on what this data indicates, the motor will perform a specific…
An ignition coil is a transformer that is used to convert and supply enough current to the spark plug to produce a spark and start the engine. It is a key part of the car’s ignition system, and if it is faulty, your car won’t start. Therefore, if this part fails, you could have serious…
In modern vehicles, dozens of sensors, solenoids, and valves keep everything working as it should. One of these solenoids is the idle control valve, also known as the IAC valve. While it may not be the most glamorous component in your engine, it keeps everything running smoothly and if it starts to fail, you’ll want…
For an engine to function properly, it must remain completely sealed. To do this, a valve cover and gasket are used. However, over time, the gasket and valve cover cannot withstand the stress causing them to fail. Without this cover in place, the valve components are left unprotected. Fortunately, this part does not fail regularly,…
If you are looking to create a new look for your vehicle, you may have thought about powder coating your wheels. Before you decide to move forward, it’s helpful to ask a few questions first. For example, how much does it cost to powder coat wheels? In this guide, we take a look at the…
While there are many ailments that can slow your vehicle down, one of the most common with newer vehicles is a faulty EGR valve. Although these EGR valves have environmental and performance benefits, they are notorious for clogging. If you think your vehicle might have a faulty EGR valve, read on and we’ll break down…
Today’s vehicles are equipped with a significant number of sophisticated components, many of which are designed to reduce a vehicle’s carbon footprint. This was, of course, necessary due to the implementation of very strict new emissions standards in the 1970s and 1980s. Car manufacturers were forced to comply or face heavy fines. One of…
The oxygen sensor, also known as the lambda sensor, is an essential sensor for the performance of your car. It measures the amount of oxygen in the gases leaving your car through the exhaust. Dr. Gunter Bauman created this sensor in the 1960s while working for Robert Bosch GmbH. But like any other mechanical equipment,…
