Glossary: Engine Blocks and Cylinder Heads

A distributor pump design that uses two or four plungers arranged opposite one another inside a cam ring to pressurize fuel; also known as opposed plunger pressurization .

A category of EMI caused when radio waves induce current into wiring or electrical components that act as a receiving antenna.

A concept used by a heat exchanger to extract heat from low-temperature fluids or gases and then convert the heat of evaporation into another form of power. A Rankine cycle device frequently contains a fluid with a low boiling temperature that evaporates, and its energy is transferred to another device.

Optimizing the injection discharge curve to best match engine operating conditions.

An injection strategy that carefully regulates the amount of fuel injected into a cylinder per degree of crank angle rotation.

The power output of an engine measured at the maximum engine speed.

An engine’s maximum speed with a load.

Sensor with an output signal that changes in proportion to the supply voltage. A potentiometer is an example of this kind of sensor.

See logical faults .

Also known as reactive resistance ; it is current induction in a coil of wire that is caused by the movement of expanding or collapsing magnetic fields. Induced current resists the inflow of supply current to the wire coil.
