Compression ratios are often between 14:1 and 23:1 for direct injection diesel engines, and between 18:1 and 23:1 for indirect injection diesel engines. At the lower end of 14:1, NOx emissions are reduced at a cost of more difficult cold-start. [6] Mazda's Skyactiv-D, the first such commercial engine from 2013, used adaptive fuel injectors ...
The M297 is based on the M120 engine but has been tuned by AMG for use in high-performance sports cars. It was offered as a 6.9 L (6,898 cc) version with a bore and stroke of 89 mm × 92.4 mm (3.50 in × 3.64 in), respectively, and was only available in the road-legal version of the CLK GTR. [2]
In effect, the formula reduces the legal weight limit for shorter trucks with fewer axles (see table below). For example, a 25-foot (7.6 m) three-axle dump truck would have a gross weight limit of 54,500 pounds (24,700 kg), instead of 80,000 pounds (36,000 kg), which is the standard weight limit for 63-foot (19.2 m) five-axle tractor-trailer.

For 2005 model year heavy-duty engines, the NTE emission cap for NMHC plus NOx is 1.25 times 2.5 grams per brake horsepower-hour, or 3.125 grams per brake horsepower-hour. The basic NTE control area for diesel engines has three basic boundaries on the engine's torque and speed map.
1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).
A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines. This is because of their ability to operate at very high speeds.
Centurion 1.7 installation in a Diamond DA42 Centurion 1.7 (TAE 125-01) The first product introduced by Thielert, a 1689 cm³ (103 in³) engine producing 135 PS (99 kW) is an inline-four engine based on the Mercedes-Benz OM668 from Mercedes-Benz A-Class A 170 CDI (W168) with 80 mm bore and 84 mm stroke.
The Wärtsilä RT-flex96C is a two-stroke turbocharged low-speed diesel engine designed by the Finnish manufacturer Wärtsilä. It is designed for large container ships that run on heavy fuel oil . Its largest 14-cylinder version is 13.5 meters high, 26.59 meters long, weighs over 2,300 tonnes , and produces 80.08 megawatts .
