To determine if repair is possible or replacement is necessary perform the following procedure. Flowchart for Repair or Replacement of Electronic Unit Injector To remove the injector, complete the following steps: Loosen the injector wire terminal screws two full turns and remove the terminal wires. Remove injector hold down crab. Lift the injector from [...]
Advantages Good performance on engines normally pulse turbocharged with two (or one) cylinders per turbine entry Disadvantages Poor performance at very low speed and load Only suitable for engines with certain numbers of cylinders (e.g. four, eight, sixteen)
Advantages High turbine efficiency, due to steady flow Good performance at high load Simple exhaust manifold Disadvantages Low available energy at turbine Poor performance at low speed and load Poor turbocharger acceleration Applications Large industrial and marine engines operating at steady speed and load, highly rated; two- and four-stroke
Advantages High available energy at turbine Good performance at low speed and load Good turbocharger acceleration Disadvantages Poor turbine efficiency with one or two cylinders per turbine entry Poor turbine efficiency at very high ratings Complex exhaust manifold with large numbers of cylinders Possible pressure wave reflection problems (on some engines) Applications Automotive, truck, marine [...]
These turbochargers are characterized by having axial flow, single stage, turbines and are fitted to the majority of large industrial and marine engines, both four- and two-stroke. The duty cycles of these engines are more arduous than that of automotive engines and they tend to spend much more of their operating time at high load. [...]
Turbochargers designed for small industrial and marine engines, though larger than those of large truck engines, are similar in concept to the automotive turbochargers described above. Radial flow compressor and turbines are used, with an inboard bearing arrangement. Apart from the larger size, they are required to have greater durability and higher efficiency. Thus the [...]
The compressor impeller is an aluminium alloy (LM- 16-WP or C-355T61) investment casting, with a gravity die-cast aluminium housing (LM-27-M). The design of the impeller is a compromise between aerodynamic requirements, mechanical strength and foundry capabilities. To achieve high efficiency, and minimum flow blockage, very thin and sharp impeller vanes are required, thickening at the [...]
Turbochargers in this class are used for passenger car diesel engines rated at 45 kW upwards to larger special heavy truck and construction vehicles rated at up to 600 kW. The most important design factors are cost, reliability and performance. To keep cost low, the design must be simple, hence a single stage radial flow [...]
The vast majority of current diesel engines operate on the four stroke principle in which combustion occurs only every other revolution, again in the region of top dead centre (TDC), and with the intermediate revolution and its associated piston strokes given over to the gas exchange process. In practice the exhaust valve(s) open well before [...]
