A vehicle is composed of easily over a thousand parts, and familiarizing the majority of these parts will add more to your knowledge of car parts. Hopefully, you’ll know what part to change when something goes wrong. For this session of “Knowing your Car”, we’ll dive in more with the piston,U-Bolt and air duct.
As one of the many moving parts inside your engine, the piston is connected to the crankshaft via the connecting rod, which prevents the cylinder bore to wobble. Note that the piston rings located at the side eliminates the possibility of engine oil leaking into the combustion chamber.
The piston is responsible for sucking in the air, compressing the air-fuel mix and pushing the waste gases out of the cylinder. Notably, a different piston is used when the engine is either (a) naturally aspirated or (b) using a power adder i.e. turbo, supercharger and/or nitrous oxide. The durability of the piston is dependent on how much power you push your engine to produce.
Unburned fuel can deposit on the piston and cylinder, which can accumulate over time. So every time you overhaul your engine, make sure you clean the soot and dirt that can diminish the performance of your engine.
Primarily found in leaf springs, U-Bolts are used to clamp tubing, steel bars and strips together. There are four elements of a U-Bolt that you should take in account every time you replace them: material, thread dimensions, inside diameter and inside height.
Also known as the air intake, the air duct is the passage of air that leads to the engine. It is mainly comprised of the following: an air filter, the mass flow sensor and the throttle body.
These are the basic components of an air intake, particularly for fuel-injected engines found in most modern vehicles. For carburetted engines in older vehicles, the mass flow sensor is lacking and an altogether different method of tuning for fuel injection is needed.
