Diesel Common Rail Injection

Diesel Common Rail Injection - Runs on all Phones & Tablets
(Electronics Components Explained)
(An Automotive Diesel Series - Book 1)
By MANDY CONCEPCION

This book contains a wide array of automotive applications. Emphasis is placed on a practical approach, with the theory to back it up as well. It is, however, expected that the technician already has a basic understanding of automobiles and electronics in general. The text is also a great companion to in class training. With that in mind, learn and enjoy.

Table of Contents

Diesel Common Rail Injection, Facts 1 (Presents a detailed analysis of Diesel Common Rail fuel injection systems. It explains te differences between older and newer Diesel Systems, the detailed anatomy of the injection as in multiple injection events, explores the pressure variables, and more about this type of Diesel Injection system.)

Diesel Common Rail Injection, Facts 2 (Concentrates on the particulars of the Diesel Injection Pump, both high pressure and low, explains the fuel rail pressure sensor operation and how it ties with the electronic system. It also touches on common issues of back leakage seen on these systems.)

Diesel Piezo-Electric Injector Operation (Goes deep into the operation of the Diesel Piezo Injector. It explains the difference between the coil or magnetic injectors, seen on gasoline engines and the piezo or crystal injector. Talks about the multi-event nature of the pulse and shows how pressure multiplication triggers the injector.)

Diesel Piezo-Electric Injector Driver-Transistor (Explains in detail how the piezo-injector is triggered from within the E CM. Shows how actual transistor drivers react electrically (push-pull transistor arrangement) to trigger the piezo-device. You'll also see the dual polarity triggering nature of the piezo injector circuit permitting what's called a partial pintle lift.)

Diesel Electric Injector Voltages (Explain the dilation of the Diesel piezo injector and the voltage characteristics of the injector pulse. Here you'll understand why a 100 volt initial pulse is applied, then how the small chamber actuates the main pintle. We also touch up on current amperage values.)

Diesel Injector Pulse and Pressure (Goes into the effective inertia of the piezo stack and why there's no clicking noise from these injectors, how precise they are, explain the high pressures and voltages needed such as 400 volts and amperages of -20 to +20 Amps.)

Diesel Injector Pulse Anatomy (Explains the Tourmaline or piezo-injector pulse analysis down to a very detailed form. Covers the pulse duration down to the mili-second, its fuel pressure, discuses idle and emissions reduction and multiple injection events.)

Diesel Fuel Pressure Regulator Operation (Goes into details on the Diesel injection fuel pressure regulator solenoid valve. Discuses the fuel pressure sensor feedback, covers duty-cycle signal, proportional or inversely proportional, relationship of duty-cycle to pressure and some safety tips.)

Diesel Injection Pressure Sensor (Detailed explanation of how the ECM controls injection pulse by controlling pressure. Covers in detail the pressure sensor - different than other sensors - output signal down to the specific waveform analysis. Gives you a deep correlation of voltage to pressure and the entire pulse pressure cycle.)

Diesel Pressure Sensor Testing (Explains in details the electrical characteristics and the Diesel piezo injection pressure sensors, linear feedback to the ECM, reference voltage, sensor ground and signal line. Get an insight on KOEO signal voltage and the standard electrical values seen with these systems.)

BONUS - Accelerator Pedal Position Sensor (Explains the operation o the APP sensor for either the Diesels or gas engines. This multi-potentiometer sensor (for redundancy) and the throttle computer are the hart of the modern electronic throttle control system.)
