Turbocharged HCPC engine scheme. 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.
Section of the MkII Clarke-Brayton split-cycle engine. Motiv Engines, LLC introduced the second-generation of its engineconcept dubbed the MkII Clarke-Brayton Engine, which it intends to develop into a heavy-duty on-highway engine fueled by liquid natural gas (LNG). Note the three different cylinder sizes.
The OP4 light-duty opposed-piston diesel. Achates Power, which is developing a family of two-stroke, compression-ignition (CI) opposed-piston (OP) engines, has designed and is developing a light-duty dieselconceptengine, the OP4. Achates started with a 1.06L/cylinder engine configuration, then moved up to a 1.6L/cylinder
FEV) a leading developer of advanced powertrain and vehicle technologies, will exhibit a lean burn engineconcept at the SAE 2011 World Congress that has been modified to run on Compressed Natural Gas (CNG). FEV developed ATAC more than a decade ago, targeting large-bore engines in stationary and heavy-duty applications.
Schematic model of a wave disk engine, showing combustion and shockwaves within the channels. The wave disc engine, a new implementation of wave rotor technology, was earlier developed by the Michigan State group in collaboration with researchers from the Warsaw Institute of Technology.

The work was conducted by a collaboration including industrial partners Arup, Dearman Engine Company, E4 Tech, Highview, Messer Group and Ricardo, as well as academics from the Universities of Leeds, Birmingham, Strathclyde, Brighton and Imperial College London.
The first registrant in the Challenge is Libralato Engines, developer of a novel rotary engine (cutaway shown) promising a 5.5% gain in combustion efficiency and 50% reduction in NO x emissions. Libralato Engines. One engine developer has already registered for the Challenge: Libralato Engines.
Schematic of downsized and supercharged four-stroke hybrid pneumatic spark injection engine. The reduction in fuel consumption is obtained mainly through enabling the effective use of a heavily downsized engine, rather than from regenerative efficiency. The hardware concept.

Researchers at the Dalian University of Technology have proposed a novel method to control premixed charge compression ignition (PCCI) phasing in internal combustion engines in all load operations. The application of HPE is also beneficial to the fuel consumption and emissions because of its several flexible operation modes.
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.
At NACV 2017, Bosch is also showcasing several future-focused powertrain conceptsengineered to save fuel and money while extending the lives of fleets. The design calls for a scalable battery that makes an all-electric driving range feasible, enabling zero local emissions driving in city centers. Thermal management.
An engine that provides vehicle manufacturers with an immediate solution for low emission legislation will make its European debut at the Engine EXPO in Stuttgart. The split-cycle engine from the Scuderi Group offers high efficiency standards without the need for large investments to modify existing production processes.
Rendering of the Grail Engine. Grail Engine Technologies , the designer of a two-stroke engine using forced semi-homogeneous charged compression ignition (FS-HCCI) combustion, has adopted the Pulstar pulse plugs from Enerpulse ( earlier post ). Elements of the Grail Engine. Click to enlarge. Matthew Riley.
The partnership involves using select conventional vessels from EPS’ existing tanker fleet that use MAN engines to be retrofitted, allowing them to be powered by methanol and ammonia which will be supplied by OCI. Also, EPS will construct newbuild vessels with MAN engines powered by the same two alternative marine fuels.
The engine is packaged as a research engine, with easy access for instrumentation, a balancer shaft, etc., The Scuderi Group unveiled a cutaway model of the first proof-of-concept prototype for its Scuderi Split-Cycle Engine ( earlier post ) at the SAE World Congress in Detroit. Model of the working prototype.
