HCCI is a combustion regime in which well-mixed fuel, exhaust gas and air are compressed to the point of auto-ignition. Unlike a spark ignition gas engine or diesel engine, HCCI produces a low-temperature, flameless release of energy throughout the entire combustion chamber.

A German company, vv-tec GmbH , is developing a compact piston-driven turbine—the Reinhardt Turbine, named after its inventor—that it says is a two-cycle (gas and steam) thermodynamic process machine that can be built with conventional components and can achieve efficiency of at least 60%. The engine components are contained within a sphere.

Since internal combustion engines will remain the primary mode of choice for mobility in the foreseeable future, both alternative (renewable) fuels and high-performance combustion concepts/ engines using fuels adapted for that purpose will be preferred for reducing the combustion impact on climate change.

A cryogenic engine such as the Dearman piston engine produces zero emissions at the point of use; has low greenhouse gas emissions provided the liquid air or nitrogen is produced from low carbon electricity; has energy and power density on a level with battery electric technology; and has the potential for rapid refueling.

The combination of discrete, asymmetrically sized cylinders and fully variable valvetrain promises the ability to vary displacement ratios, bore-stroke ratios, compression-expansion ratios, compression-expansion phasing, and gas transfer phasing for engine optimization—i.e., a more efficient internal combustion engine.

Furthermore, natural gas will be investigated as the fuel of the system. The control method of linear generator and the movement of free-piston will be investigated, and special attention will be [paid to] the synchronization of th left and the right pistons. —Huang et al.

Each cylinder fires twice per revolution and two cylinders fire simultaneously, resulting in four times the output per revolution of a conventional four-stroke engine at the same displacement. The engine can be adapted to run any combustible gas or liquid as fuel. Tags: Concept Engines. OX2 in a test rig.

Although the HPE approach can in concept be applied to both spark ignition (SI) and compression ignition engines (CI), after an evaluation of engine types, the team decided that downsized SI engines offered the best target for an HPE application. The concept engine uses the Bosch electro-hydraulic valve system (EHVS).

It compresses the pressurized gas produced by exhaust gas turbocharger, comprising fresh air and exhaust gas introduced from the EGR valve. Compound HPE is divided into a compressor cylinder and a power cylinder, combined with a compressed air storage tank. Then it charges the compressed air storage tank.

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.
