By 1931 Pratt & Whitney had started a development of their single-row Wasp nine-cylinder engine into the larger and much more powerful fourteen-cylinder, twin-row R-1830 Twin Wasp with a similar 1,800 in 3 (30 L) displacement that would easily compete with the single-row Cyclone. In 1935 Wright followed P&W's lead, and developed larger engines ...
The engine is the largest reciprocating engine in the world. The 14-cylinder version first entered commercial service in September 2006 aboard the Emma Mærsk . The design is similar to the older RTA96C engine, but with common rail technology (in place of traditional camshaft , chain gear , fuel pump and hydraulic actuator systems).
A connecting rod, also called a 'con rod', [1] [2] [3] is the part of a piston engine which connects the piston to the crankshaft. Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. [4] The connecting rod is required to transmit the compressive and tensile forces from ...
An early example is the 3.3 L (200 cu in) and 3.8 L (229 cu in) Chevrolet 90° V6 engines, which have an 18° offset crankshaft resulting in an uneven firing interval. Newer examples, such as the Honda C engine, use 30° offset crank pins, resulting in an even firing interval. As per V6 engines with 60° V angles, these engines have primary ...

Deep rolling is a method of cold work deformation and burnishing of internal combustion engine crankshaft journal fillets to increase durability and design safety factors. Compressive residual stresses can be measured below the surface of a deep-rolled fillet. Other types of fillets on shafts or tubes can also benefit from this method.
Over a period of time, Detroit Diesel continued to further evolve the design of the engine. They finally brought the engine up to 137.5 hp (102.5 kW) per cylinder and 406 lb⋅ft (550 N⋅m) torque per cylinder; needless to say, this is a considerable amount of power coming from 149 cu in (2.4 L) per cylinder.
The 2.0L DOHC inline four-cylinder gasoline engine is capable of 158 hp (118 kW) and produces 141 lb⋅ft (191 N⋅m) of torque. The engine has a displacement of 2.0 L; 121.9 cu in (1,998 cc) with a bore and a stroke of 3.38 in × 3.38 in (86 mm × 86 mm). [2] The compression ratio of the engine is 10.5:1. [2]
