The two main parts of any engine are its cylinder head and engine block. The block contains the pistons and cylinders, while the cylinder head contains the rocker arms and valves. In between the block and cylinder head is the cylinder head gasket. This gasket serves as a seal for all the cylinders inside the block. What is the purpose of heads on an engine?
They’re key to controlling air flow in and out of the cylinders and fuel deployment. The cylinder head also holds the injectors and valves – and contains more moving parts than any other part of the engine. Although largely unnoticed, the cylinder head plays a key role in your engine.

What are the types of cylinder head?
The cylinder head may be classified depending upon the layout of valves and ports. There are mainly three types – Loop-flow type, offset cross-flow type or in-line cross-flow type. In the loop-flow design, the inlet & exhaust manifolds are on the same side which helps pre-heating of the intake air. How many heads does a car have?
Cars with inline (straight) engines have one cylinder head and automobiles with V engines have two cylinder heads, one for each cylinder bank. In some vehicles, where cylinder banks are very close to the V engine, one cylinder is all that is needed. Large industrial vehicles may have one head per cylinder.

Can a dead cylinder be fixed?
With only one broken cylinder, yes you can, but it isn’t recommended. Driving with the engine having a misfired cylinder can be potentially dangerous. You’ll already be low of power with one cylinder if not firing and if you another cylinder goes out, then you lose more power.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
