MAN 51031016891 cylinder head

Description

The MAN 51031016891 is a cylinder head, a critical component of an internal combustion engine. It sits atop the engine block, sealing the cylinders and housing the valves, spark plugs, and fuel injectors. This part is responsible for controlling the flow of air and fuel into the combustion chamber and the exhaust gases out of it. Manufactured in Germany, this cylinder head is designed for optimal engine performance and durability. Its dimensions are 100 x 180 x 247 mm. The robust construction and precise engineering of this cylinder head contribute to improved combustion efficiency, reduced emissions, and enhanced engine reliability.

Key Features & Benefits

Basically, it seals the top of the cylinders in your engine. It houses all the valves, spark plugs, and intake and exhaust ports. Fuel and air come in through those ports, get mixed, the spark plug ignites it, and the resulting explosion pushes the piston down. The cylinder head is where all that controlled combustion happens. It also has coolant passages running through it to help manage engine temperature and oil passages to lubricate everything up top. It’s a core part of your engine – you can think of it as the engine's “top end.” It works directly with the pistons, connecting rods, and crankshaft to turn fuel into motion. Everything from how smoothly your engine runs to how much power it makes relies on a good cylinder head. It’s a critical component in the entire process of powering your vehicle.

Symptoms, Risks & Replacements

Well, if the cylinder head fails, things go downhill fast. You’ll notice if you have a blown head gasket – often it starts with overheating, white smoke from the exhaust, or coolant mixing with the oil. Even a small crack can lead to a loss of compression, which means less power and reduced fuel economy. It acts like a shield, keeping everything contained, so if that seal is broken, you’re looking at serious engine damage. Keeping it in good shape is essential for a reliable engine. You can often find replacements pretty easily, places like Fixparts Online have a good selection. It’s definitely one of those parts you don’t want to put off repairing if you suspect a problem.
