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.

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 H-engine—basically two separate engines housed within the same engine block—comprises two switchable parallel piston banks, independently fueled by gasoline and CNG. Startup Eco-Motive has developed what it calls the first dual-fuel “H” engine; it recently received a patent (# 8807098 ) on the design.
Achates Power was recently awarded a $5-million contract from the US Army to expand the family of opposed-piston engines for military vehicles. The project, awarded in late-2020, builds upon the success of the Advanced Combat Engine (ACE). to develop the Advanced Combat Engine for the US Army. Earlier post.)
While most push belt type CVTs fail at around 300 N·m (221 lb-ft) of torque, he says, the FPCVT in this patent will be best suited for the market of 300 N·m+ engines. Hawthorn is looking for funding and support to build a prototype. Tags: ConceptEngines Transmissions. FPCVT website.
The joint project is a multi-year development program in which Ballard and MAHLE will continuously refine Ballard’s compact, energy-dense fuel cell stack and an integrated engine to meet the quality and performance expectations of the truck industry.
Topics addressed include: advanced batteries (including manufacturing processes) and electric drive R&D; Lightweight materials; Advanced combustion engine and enabling technologies R&D; and Fuels technologies (dedicated or dual-fuel natural gas engine technologies). less than a baseline structure. turbomachinery.
The ETI is a public-private partnership between global energy and engineering companies—BP, Caterpillar, EDF, E.ON, Rolls-Royce and Shell—and the UK Government. This project builds upon the HDV Efficiency Focus Area feasibility study completed in 2010. million (US$3.9-million)
Dutch start-up ECONAMIQ is developing a novel engine technology which saves up to 20% in fuel consumption. The “ECONAMIQ principle” uses flexible over-expansion in combination with cylinder deactivation technology to increase performance and efficiency without significantly changing the engine layout or architecture.
UK-based Libertine FPE has built a demonstration prototype of its linear electrical machine for what it is calling “Digital Piston Motion Control” in free piston engine applications. This technology will allow researchers to develop future combustion engines free from the piston motion constraints dictated by the crankshaft.
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.
