Bosch leading Direct4Gas consortium to develop direct injection for monovalent natural gas engines

Green Car Congress

Bosch is leading a consortium in a German government-funded project to develop a direct injection system for monovalent natural gas engines—i.e., The very high octane rating and resulting high resistance to knock is promising for small, supercharged, downsized SI engines. engines that run exclusively on CNG. million (US$4.3

Mazdas new SKYACTIV gasoline and diesel engines are steps on the road to its Ideal Engine; focus on compression ratio

Green Car Congress

However, while Mazda plans to offer hybrid vehicles in the medium-term, its engineers are pushing hard to increase the efficiencies of both the gasoline and diesel platforms, moving toward what they call “the ideal Internal Combustion Engine.” Extreme compression ratio rather than downsizing. Although downsizing—i.e.,

Why Maruti exited the diesel market | Autocar Professional

Baua Electric

Why did Maruti Suzuki spend five years and around Rs 1,000 crore designing and developing its very own diesel engine, only to withdraw it from the market within a year of its launch? It’s a nagging question that hasn’t been answered properly, at least not by the company, which abruptly stopped selling diesel cars in April 2020.

KIT researchers developing low-pressure carbonitriding process for hardening steel with methylamine; applications in downsized engines

Green Car Congress

The new low-pressure carbonitriding (enriching low-alloy steels with carbon and nitrogen) process saves time and process gas. Steels hardened in this way are suited for use in components subjected to high mechanical and thermal loads in downsized, energy-efficient and low-emission engines of the future. ethyne or propane.
