Here is your scrumptious A-list of simple car engine diagram for dummies. Every part under the hood is explained with a labeled diagram of car engine. This page will explain mainly how an internal combustion engine works in your car with a diagram, how the engine starts when you twist the key in the ignition with your hand, and why sometimes car engine won’t start online. The engine diagram shown here is a petrol engine that has been dissected for easier understanding. Here we go!

car engine diagram On average, there is about 3,000 feet of electrical wiring in every car. Do not let this wiring scares you, this article we will just talk about engine parts. The diagram here shows a gasoline-powered engine that has been dissected. Here we will break down to four major parts which is power parts, fuel parts, spark parts, lubricant parts.

Power parts in a car engine included parts that play a big role during the combustion such as the piston, camshaft, rocker arm, hydraulic adjuster, intake valve, exhaust valve, connecting rod, crankshaft, crankshaft sprocket, timing belt tensioner, timing belt, cam sprocket, cylinder block and among others. Without any of these parts, the combustion will not be able to run a gasoline-powered engine.

For fuel parts, an engine can either run with carburetor fuel system or fuel injection systems. Most of the cars that newer than mid 90’s are running on fuel injection system. The fuel system is connected to the fuel tank through fuel lines and the function is to blend proper air and fuel into the engine for better combustion. As you can see from the car engine diagram, generally the fuel system is placed on top of the engine.

Let’s move on to the spark parts where the engine runs. Whenever you turn on the ignition with your key, it connects the battery with coil, distributor, and also spark plug. The spark plug turn the battery power to spark inside the engine and the combustion begins when these sparks meet fuel. Let’s not forget about the alternator that fitted to the engine. The function is to recharge the battery while the car is running to keep the battery power.

Last but not least, the lubricant inside an engine. An engine could not be run without engine oil, coolant, and oil. The oil pump and oil filter is those parts that deal with the oil. When combustion happens inside an engine, it needs coolant to cool down the temperature, therefore the engine needs a radiator, water hose, water pump, as well as thermostat. Here then you have finally learned how an engine work with a simple car engine diagram.
