Unit Injector (UI)
Share
Unit Injector (UI) is a high pressure integrated (into a cylinder head) direct fuel injection system for diesel engines represented by a single component that combines the injector nozzle and the injection pump.

Starter Motor
Starter Motor is a component of the vehicle starting system developed to start the engine by turning its flywheel which is connected to the crankshaft.
moreFlywheel
Flywheel is a large metal disc which is bolted onto one end of the crankshaft developed to store spinning kinetic energy that keeps the engine rotating on the non power strokes.
moreIntake Manifold
Intake Manifold or Inlet Manifold is the part of an engine representing a group of pipes that supplies the fuel-air mixture to the intake valves of the cylinders of an internal-combustion engine.
moreThermal Expansion
Thermal Expansion is the process of increasing in volume of a material as its temperature increases. Thermal expansion has to be taken into account in engineering of vehicle components because the different rates of thermal expansion of the two metals can cause problems.
moreExhaust Manifold
Exhaust Manifold is the first part of vehicle's exhaust system designed to collect the exhaust gases from multiple ports on the engine's cylinder head, conveying them towards the catalytic converter.
moreNanoslide®
Nanoslide® is an innovative technology, patented by Mercedes-Benz, designed to reduce the fuel consumption and CO2 emissions of internal combustion engines and represents an extremely thin, low-friction coating that is applied to the inner surfaces of the cylinders in an aluminium engine block.
moreLow-speed Pre-ignition (LSPI)
Low-speed Pre-ignition (LSPI) is an early combustion event that takes place in gasoline engines, while operating at low speeds and high loads, when fuel burning takes place during the compression stroke.
