Automotive Engine System

Combustion Chamber

After the piston reaches top dead center of its top and the space between the cylinder head, fuel that is burning in this room.

Compression Ratio

The cylinder piston in the next dead divided by the total volume of piston top dead center in the total volume (combustion chamber volume), the value obtained is called the compression ratio.

    Connecting Rod

Engine crankshaft and piston connecting rod connection.

Cooling System

By means of the coolant loop, the excess heat out of the engine to prevent overheating of the system. In the water-cooled engine, including the water jacket, water pump (someone now Your ㄡ ‘), water tanks and thermostat.

Crankcase

Engine lower, as the crankshaft running the place, including the cylinder block of the lower and oil pan.

Crankshaft

The main rotating engine parts, installed after the upper link can carry up and down the connecting rod (reciprocating) movement into a cycle (rotation) movement.

Crankshaft Gear

Crankshaft gear mounted on the front or the key gear, often used on behalf of the moving cam gear, chain or toothed belt.

Cylinder Block

The basic structure of the engine, the engine all the Parts and Accessories are installed in the aircraft parts, including engine cylinder and upper crankcase.

    Cylinder Head

Closed the lid and steam engine parts missing, including the water jacket and steam valve and the cooling film.

Detonation

For the impact or fire crackling in the spark ignition engine combustion chamber, because the air pressure over the fuel mixture will be spontaneous, so a portion of unburned mixture of air to avoid the secondary ignition (after the spark plug ignition), which issued a pop.

Displacemint

A cycle in the engine operation, can all mixture into the air and the ability of all cylinders, but also refers to the operation of a piston from a stroke to another stroke volume can row.

Engine

A kind of heat energy into mechanical energy can machine: a machine can be powered by fuel burning device; sometimes as a motor.

Fan Belt

A kind of belt-driven by the crankshaft, the main purpose is to drive the engine fan and water pump.

    Float Level

Carburetor float room, float float and withstand the needle, plug into the ports, so that oil is not flowing into float chamber, the oil level.

Four-Stroke Cycle

Intake, compression, power, four stroke exhaust. Transfer a complete four stroke cycle.

Gasket

Paper, rubber sheets or copper sheets, placed between two planes to strengthen the sealing material.

Gear Lubricant

A kind of gear lubrication oil can, usually SAE90 No. oil.

Heat-Control Valve

A Day in the engine exhaust manifold temperature operation of the valve can not reach normal operating temperature before the engine will exhaust the heat into the intake manifold.

Knock

The metal with the engine speed crash, usually caused by loose or worn bearings produced.

Main Bearing

Engine crankshaft bearings within the support.

Manifold Pressure

Turbocharger in operation within the intake manifold pressure.

Manifold Vacuum

Means within the intake manifold vacuum, that the cylinder during the intake stroke of the vacuum generated.

Oil Pan

At lower engine: removable and sealed by the axle box as a storage tank shell.

Oil filter

A kind of passage in the engine oil filter could be dirt under the device.

Oil Pump

In the lubrication system can force the oil from the sump engine moving parts of the device sent.

Ping

Engine acceleration produced by detonation, the ignition timing advance due to too many or too low octane fuel due.
