Schematic of the conceptual ideal piston engine used for the TCR study. When reforming is not used, the fuel and exhaust pass through CV2 unchanged. The basic concept of TCR involves using exhaust heat to promote on-board reforming of hydrocarbon fuels into syngas (a mixture of carbon monoxide and hydrogen).

The family of engines strategy uses a common power cylinder system across several different engine variants to address a range of power and torque requirements in order to serve multiple military vehicles with a common architecture. In December 2020, Achates Power announced that their 10.6L

A team from Universita degli Studi di Pisa (Italy) and Rolf Reitz at the University of Wisconsin-Madison are proposing a novel combustion concept—Homogenous Charge Progressive Combustion (HCPC)—based on a split-cycle principle to control HCCI combustion in diesel-fueled engines. —Musu et al., SAE 2010-01-2107.

Secondly, the central combustion chamber is benefit for highly efficient scavenging via intake and exhaust ports without using valves. In an SAE paper, Huang describes a modeling and simulation study of the new free-piston linear generator. For further study, an accurate model of the linear generator and combustion will be developed.

An adaption of cylinder de-activation technique called ECONAMIQ over-expansion can be applied to engines to improve fuel efficiency. Using the pressure from the exhaust gas from the active cylinders, the ‘idle’ cylinders could be expanded to extract more work out of the engine during partial load operation. de Jong (2019).

It compresses the pressurized gas produced by exhaust gas turbocharger, comprising fresh air and exhaust gas introduced from the EGR valve. For the current study, the engine was derived from a single-cylinder, naturally aspirated, high-speed direct-injection (HSDI) diesel engine with a displacement of 0.418 L.
