STEP 2: ENGINE TYPE
Tool Tip
Gas Engine VehicleAn internal combustion engine that runs on a gaseous fuel, such as coal gas, producer gas, biogas, landfill gas or natural gas.
Gas Engine Vehicle
Tool Tip
Diesel Engine VehicleAn internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to the mechanical compression (adiabatic compression).
Diesel Engine Vehicle
Tool Tip
Small EnginesA general term for a wide range of small-displacement, low-powered internal combustion engines used to power lawn mowers, generators, concrete mixers and many other machines that require independent power sources.
Small Engines
Tool Tip
Marine EnginesTypes of automobile petrol- or diesel engines that have been specifically modified for use in the marine environment.

STEP 2: ENGINE PERFORMANCE
Tool Tip
Turbo ChargedA turbine-driven, forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra compressed air into the combustion chamber.
Turbo Charged
Tool Tip
Super ChargedAn air compressor that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing power.

STEP 2: ENGINE COMBUSTION TYPE
Tool Tip
2 StrokeA type of internal combustion engine which completes a power cycle with two strokes (up and down movements) of the piston during only one crankshaft revolution.
2 Stroke
Tool Tip
4 StrokeAn internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction.

STEP 3: WHAT TYPE OF FUEL SYSTEM DO YOU HAVE?
Tool Tip
Gasoline Direct InjectionA mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber.
Gasoline Direct Injection
Tool Tip
Port InjectionThe spraying of the fuel onto the back of the intake port, which speeds up its evaporation.
Port Injection
Tool Tip
CarburetorA device that mixes air and fuel for internal combustion engines in the proper air–fuel ratio for combustion.
Carburetor
Tool Tip
Diesel Direct InjectionCommon rail direct fuel injection is a direct fuel injection system for diesel engines. It features a high-pressure (over 100 bar or 10 MPa or 1,500 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles)

STEP 4: FUEL TYPE
Tool Tip
GasolineGasoline or petrol is a colorless petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines. It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives.
Gasoline
Tool Tip
e85 flex fuelFlexible fuel vehicles (FFVs) are designed to run on gasoline or gasoline-ethanol blends of up to 85% ethanol (E85).
e85 flex fuel
Tool Tip
DieselAny liquid fuel used in diesel engines, whose fuel ignition takes place, without any spark, as a result of compression of the inlet air mixture and then injection of fuel.
