crank angle

In addition, the required crank angles of the forward and reverse strokes are no longer equivalent.

The four points in the graph indicate the crank angle in degrees.

Straight-three engines generally employ a crank angle of 120 .

Position with respect to crank angle (by rearranging the triangle relation):

The timing is measured in degrees of crank angle of the piston before top dead centre.

Velocity with respect to crank angle (take first derivative, using the chain rule):

The equations that follow describe the reciprocating motion of the piston with respect to crank angle.

The crank angle has a major effect on efficiency and the best angle frequently has to be found experimentally.

Converts a piston distance from top dead centre (TDC) to a crank angle.

A customer of Hybrid Electronics manufacture crank angle sensors for the automotive electronic repair industry.

Factory Distributors and Crank Angle Sensors can usually be used without modification.

In two-stroke engines, the crank angle is generally 180 , which gives two power strokes in each revolution.

In such engines the crank angle interval over which injection can take place is limited, particularly for late injection in the compression stroke.

A change-over service is available for DELCO computers and crank angle cores.

An hydraulic vane-type actuator that continuously alters the intake valve timing and phase in relation to the crank angle.

Since four-cylinder engines have a 180 degree crank angle, cylinders 1 and 4 exhaust their gases at different times than cylinders 2 and 3.

Using the information gained from these analyses, the initial crank angles that would result in the highest drive torque requirement for the two start-up/shut-down times are found.

This means that the crank angle required to execute a forward stroke is equivalent to the angle required to perform a reverse stroke.

Crank Angle Sensors : Function: Modern engine management systems require accurate information about crankshaft speed and exact position.

Both the intake and exhaust VANOS or variable valve timing units had 50 degree crank angle adjustment.

Additionally, in 1996 the cam angle sensor in the distributor was also replaced with a crank angle sensor to achieve a smoother idle.

This causes the start of combustion to be out of synchronization with the crank angle, meaning that the engine would only run smoothly at one low-speed or load.

The XS400 had a four-stroke, air-cooled, overhead-cam straight-twin engine with a 180 crank angle, which reduces linear vibration at the cost of some axial vibration.

From the experiments, it was shown that a 360 crank angle was better suited to the use of a single carburettor than a 180 crank angle.

Beside the fuel injection, a significant change for the Z24i was the addition of an optical crank angle sensor in the distributor rather than a vacuum advance and ignition module.
