Engine for your vehicle: important for selection

Engine: operating principle, malfunctions, repair and replacement

An engine is one of the most important units of a vehicle. It is designed to convert thermal energy into mechanical one. This unit ensures wheels rotation.

Main types

By fuel type:

  • Petrol. These engines ignite the compressed air-fuel mixture with the help of an electric spark.
  • Diesel. Their operating principle is based on the ability of sprayed fuel to self-ignite when it comes in contact with compressed air.

By the method of air supply:

  • Naturally aspirated engines. Vacuum in the engine’s cylinder ensures air or air-fuel mixture feed.
  • Turbocharged. Air or air-fuel mixture are supplied to the cylinders under pressure created by a turbocharger. This allows to increase engine power and performance.

Main components and operation specifics of the engine

Major parts of an engine are crankcase, engine cylinder block and its head. The latter has places to mount spark plugs as well as ports for air-fuel mixture intake and exhaust. These ports are closed with valves. A piston connected to the connecting rod moves inside the cylinder. The con rod is attached to the crankshaft which in turn is connected to the camshaft via timing belt or chain. The camshaft controls the opening and closing of the valves. There is a flywheel at the other end of the crankshaft, the torque of which is transmitted to the wheels by a gearbox. Moving components of the unit are lubricated with the oil from the crankcase. To prevent the ingress of oil into the combustion chambers, the pistons are equipped with special rings and the valves with stem seals.

Engine cylinder block and its head have special ports for coolant and oil. The joint between the engine cylinder block and cylinder head is sealed with a gasket.

Most common malfunctions

  • Carbon deposits on the cylinder walls and other engine components. Such deposits may build up due to worn-out piston rings or valve stem seals.
  • Worn-out components of the cylinder-piston group. This happens due to engine overheating, poor lubrication or the ingress of dirt into the combustion chambers through the EGR valve.
  • Burnt piston. This may be a result of a faulty cooling system, use of petrol with lower octane numbers, incorrect ignition timing or fuel supply advance angle, knocking, long-time glow plug ignition, injector failure.
  • Faulty valves. The failure of these components can be caused by torn timing belt or chain.

Proven ways to extend the service life of the engine

To ensure long and efficient operation of a power unit, you should timely change oil and replace oil, fuel, air filters. Only use the lubricants recommended by the car manufacturer. When replacing the engine cylinder head gasket, keep to the tightening torque for threaded fasteners specified in the technical documents. When it’s cold, let your engine warm up well before running at high RPM.

What you should know about repairing engines

The volume of work depends on the malfunction type. As a rule, it is enough to replace faulty components such as valves, hydraulic valve lifters and seals.

A major engine overhaul implies its complete disassembly. This allows to clean the motor, to rebore its cylinders or to install cylinder sleeves, as well as to replace pistons and piston rings. If the engine cylinder block or its head are cracked, they have to be replaced. If there is a gap between the cylinder block and its head, these components have to be resurfaced. As soon as the power unit has been assembled again, it should be adjusted and tested at special stands.
