It is a one-to-one relationship with an offset of -100 kPa for boost pressure. Thus, a MAP sensor will always read 100 kPa more than a boost sensor measuring the same conditions. A MAP sensor will never display a negative reading because it is measuring absolute pressure, where zero is the total absence of pressure.
A 'brake' dynamometer applies variable load on the prime mover (PM) and measures the PM's ability to move or hold the RPM as related to the "braking force" applied. It is usually connected to a computer that records applied braking torque and calculates engine power output based on information from a "load cell" or "strain gauge" and a speed ...
LHDs are available in both diesel and electric versions. The diesel version is easily transportable from one location to another and has diesel engines with a power drive of 75 to 150 HP or more. Engines are either water- or air-cooled. LHD with electric motors as drives have a general capacity of 75 to 150 HP. These are operative at a medium ...
The Elf was marketed as the Isuzu NPR and Chevrolet/GMC W series, each available with either the 4BD2T 3.9-liter turbo-diesel engine until 1998, the 4HE1 4.8-liter turbo-diesel engine from 1998 to 2004, the 4HK1 5.2-liter turbo-diesel engine from 2005.
MAF sensor in a 2006-2015 automotive diesel engine. A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its ...
A water in fuel sensor, or WiF sensor, is an electronic sensor used to indicate the presence of water in fuel. It is installed in a fuel filter . When the water level in the water separator reaches the warning level, the WiF sends an electrical signal to the ECU or to dashboard (lamp). [ 1 ]

Exhaust brakes are simpler in operation than an engine brake.Essentially, the exhaust pipe of the vehicle is restricted by a valve.This raises the pressure in the exhaust system, forcing the engine to work harder on the exhaust stroke of its cylinders, so again the engine is acting as an air compressor, with the power required to compress the air being withheld from the exhaust pipe, retarding ...
