Piston Designs in Heavy-Duty Diesels BY STEVE SCOTT Most recently, you may encounter various piston designs within heavy-duty diesel engines. As engine technologies have evolved, the demand on internal engine parts has also increased. While aluminum pistons have worked well for decades in engines with lower cylinder pressures (approx. 1,600-1,900psi), many have been replaced by articulated.
Diesel Engine System Design links everything diesel engineers need to know about engine performance and system design in order for them to master all the essential topics quickly and to solve practical design problems. Based on the author s unique experience in the field, it enables engineers to come up with an appropriate specification at an early stage in the product development cycle. DIESEL ENGINES DOE-HDBK-1018/1-93 Diesel Engine Fundamentals The Cylinder Block The cylinder block, as shown in Figure 4, is generally a single unit made from cast iron. In a liquid-cooled diesel, the block also provides the structure and rigid frame Turbocharger with EGR system turbocharged engines 200026-06 EGR cooler EGR valve Air filter Intake manifold Engine er Exhaust manifold Particulate trap NOx sensor p sensor Classification of Engines Fuel used, gasoline engines diesel engines natural gas (CNG and LNG), methane, LPG engines alcohol engines hydrogen engines. Diesel Fuels and Diesel Fuel Systems for Cat® engines listed on the cover of this section. Additional engine systems, components and dynamics are addressed in other sections of this Application and Installation Guide. Engine-specific information and data are available from a variety of sources. Refer to the Introduction section of this guide.

Applied in diesel engines design are technical solutions allowing to reduce the harmful substances impact on human health and environment, s o unauthorized modification of the engines design, breaking the manufacturer settings, disregarding technical service perio-dicity is strictly forbidden. System must be able to withstand these conditions in a failsafe way, in-cluding starting and stopping the en-gine during HFO operation. Fig. 1: CR injection system MAN 32/44CR Using just one pressure accumulator (common rail) for large bore diesel engines, extended over the entire engine length, is problematic for the following reasons:. Reference for high and medium speed diesel engines using 1-D and/or 2-D diesel fuel, and sets forth some important points to be observed. Fuel and fuel system Diesel engines can burn a wide range of fuels, depending on their design.
