Sensors and actuators of the Engine control system

A practical guide on the actuators of control systems of modern gasoline and diesel engines of passenger cars and commercial vehicles. The self-diagnosis functions and the basics of gasoline and diesel fuel injection systems are described, and then various types of электромагнитная valves ( в том числе, additional air, fuel tank venting, fuel pressure, fuel dosing, fuel pressure limitation, AdBlue dosing, variable valve timing, exhaust gas recirculation, boost pressure limitation), electric motors (e.g. fuel pump, AdBlue feed pump, secondary air pump, throttle actuator, exhaust gas recirculation flap actuator, intake system flap valves, coolant pump), heating elements ( в том числе, lambda probes, glow свечи, fuel heaters, электрически regulated thermostat, pump and AdBlue tank) and ignition coils.

The формы волны of signals from individual actuators and their interpretation, recorded in real conditions, were presented.

Recipients: engineers and technicians specializing in cars, employees of workshops and car service stations, students of universities with the automotive специализацией в области and students of high schools with an automotive режимы.

2. Engine control system sensors in workshop practice. Construction, operation and diagnosis using an oscilloscope - Gerald Schneehage, Polish, WŁ-WA 2017, ed. 2 wide, 118 pages, size 16. 5x24 см, approx. 190 illustrations, diagrams and drawings, вес 0.24 кг, soft cover

Professional guide, which describes about 30 types of sensors used in modern electronic control systems of spark ignition and compression ignition engines. Это представляет структуру, операцию и диагностику сенсоров, использующих осциллограф. Especially valuable материал are illustrations showing the signal формы волны of individual sensors, both correct and incorrect, as well as electrical diagrams of connections of individual sensors.

The second edition includes a description of the newly introduced types of sensors, such as the combustion chamber pressure sensor (built into the glow plug) and the potentiometric exhaust gas flap sensor (installed in the exhaust system after the particulate filter).

The guide is intended for мехатроники, electromechanics and car mechanics, high school students of motor vehicles, participants of qualification courses in the field of electrical and electronic vehicle systems, students and engineers specializing in automotive and all those involved in practical activities in the field of automotive technology.
