What does Dohc Mean in Car Engines

It can be difficult to know the meaning of car engine terms, especially when you’re not an engineer. In this article, we’ll take a look at the dohc engine and explain what it is and what it does.

What is Dohc?

Dohc is short for “direct injection” and it’s a type of fuel delivery system found in many car engines. In a Dohc engine, the fuel is pumped directly into the cylinders, bypassing the traditional carburetor. Direct injection increases power and efficiency by allowing the engine to burn fuel more quickly and accurately.

How Does Dohc Work?

Dohc is an acronym for direct injection. This technology uses fuel directly from the pump instead of using a carburetor and throttle body to control the amount of air and fuel mixture that goes into the engine. This system is more efficient because it eliminates the need for compression and ignition timing adjustments, which can save fuel.

Why Is Dohc Used in Car Engines?

DOHC is an abbreviation for “direct-injection”, which is a type of engine where the fuel is injected directly into the combustion chambers. This type of engine is often found in compact cars and sports cars because it offers better fuel economy and performance. Dohc engines also tend to be more reliable than other types of engines.
