What is the difference between a gasoline engine and a diesel engine?
In theory, diesel engines and gasoline engines are very similar. They are both internal combustion engines designed to convert chemical energy in the fuel into mechanical energy. This mechanical energy causes a piston to move up and down inside a cylinder. The piston is connected to a crankshaft, and the up and down motion of […]
Car manufacturers are constantly trying the following methods to make engines more fuel efficient
Increasing displacement: More displacement means more power because the engine can burn more gasoline per revolution. Displacement can be increased by making the cylinders larger or by adding more cylinders. 12 cylinders seems to be the practical limit.Increasing compression ratio: The higher the compression ratio, the more power is produced, but the higher the compression […]
The subsystem of the engine that maintains the input (oil and fuel) and output (exhaust gases and emissions).
A car’s exhaust system includes the exhaust pipe and muffler. When it comes to daily car maintenance, the first thing you might be concerned about is the amount of gasoline in your car. How does the gasoline you put in power the cylinders? The engine’s fuel system draws gasoline from the tank and mixes it […]
How a car engine starts, cools, and circulates air.
Now you know how and why an engine stays cool. But why is air circulation so important? Most cars have naturally aspirated engines, which means air passes through the air filter directly into the cylinders. High-performance, modern fuel-efficient engines are either turbocharged or supercharged, which means the air entering the engine is first pressurized (so […]
What could be the problem if you find that your engine turns over but won’t start?
There are three basic problems that can occur: a bad fuel mixture, insufficient compression, or insufficient spark. Beyond that, there are thousands of smaller issues that can cause problems, but these are the “big three.” Based on the simple engine we discussed, here’s a quick rundown of how these issues can affect your engine:A bad […]
Basic car engine parts
The heart of an engine is the cylinder, where the piston moves up and down. Most lawn mowers have a single-cylinder engine, but cars often have multiple cylinders (four, six, and eight are common). In a multi-cylinder engine, the cylinders are usually arranged in three ways: inline, V-shaped, or flat (also called horizontally opposed or […]
Truck classification
Trucks can be divided into inline trucks and articulated trucks. Inline trucks are trucks with all axles mounted on a single frame. Articulated vehicles are vehicles made up of two or more independent frames connected by suitable couplings. A truck tractor is a motor vehicle used primarily for towing a truck trailer for carrying part […]
