SEC issues cease-and-desist order against split-cycle engine developer Scuderi Group for violations of Securities Act

Green Car Congress

The Scuderi Engine is a split-cycle design that divides the four strokes of a conventional combustion cycle over two paired cylinders. The engine has two crossover passages that connect the two cylinders, which separate the four strokes of the pistons. a more efficient internal combustion engine. Earlier post.). Earlier post.).

Eastern Pacific Shipping, OCI & MAN partner to develop methanol & ammonia as marine fuels; retrofits and newbuilds

Green Car Congress

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.

Libertine FPE builds demo prototype of linear free piston generator

Green Car Congress

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.
