Head-related problems usually involve loss of compression in one or two cylinders, a condition that is signaled by a ragged idle, by increased fuel consumption,…
Examples of the energy cell, or Lanova divided chamber, can still be encountered in vintage Caterpillar tractor engines (Fig. 7-4). The cell consists of a…
The swirl, or turbulence, chamber is similar in appearance to the precombustion chamber, but functions differently (Fig. 7-3). During compression, the disc-shaped or spherical antechamber…
The precombustion chamber was first used on the Hornsby-Ackroyd lowcompression oil engine and subsequently by Caterpillar, Deutz, and Mercedes-Benz, and other diesel manufacturers (Fig. 7-2).…
Indirect injection (IDI) uses energy released by combustion to drive the fuel charge deeply into the air mass. The combustion chamber is divided into two…
Direct Injection (DI) chambers, also called open or undivided chambers, resemble those used in carbureted engines (Fig. 7-1). These symmetrical chambers have small surface areas…
The variable geometry turbocharger and the exhaust gas recirculation system are intimately related, with overlapping trouble codes. Depending upon its J 1587 addendum, flash code…
Series 50 and 60 solenoid-actuated unit injectors are replaced as assemblies, using new seals, washers, and hold-down bolts. Disconnect the battery to protect the computer…
Now in its sixth generation, DDEC (Detroit Diesel Electronic Control or “dee-deck”) was the first EMS designed for heavy-duty diesels. Later versions follow European practice…
