Renault doesn't sell any vehicles in the U.S.—unless you consider some Nissans that share a global platform—but there's a reason this tiny diesel from France is interesting: it gives us an idea of how internal combustion engines will evolve under Now the smallest (quarter-scale) blown V8 gasoline engine in commercial production is being turned The engines for such large models are usually two-cycle engines not dissimilar from the engines that power weedwackers and leaf blowers, typically Outboard engines have been around since 1896 and have done a good job of getting smaller craft from point A to point B with simple efficiency. As time has gone by the simplicity of these motors has diminished as the technology advanced. Along with greater Honey, they shrunk the diesel! Renault has unveiled a tiny two-cylinder, two-stroke diesel engine in development that could replace the four-cylinders used in its entry-level cars. The so-called POWERFUL (POWERtrain for Future Light-duty vehicles Could power Renault’s future compact models. Among various new technology concepts unveiled at the Innovations@Renault event in Paris, the POWERFUL (POWERtrain for Future Light-duty vehicles) two-stroke twin-cylinder turbocharged and supercharged diesel In a two-cycle engine, the valving is designed to take advantage of both the up and down stroke of the motor to push exhaust and fresh air through the combustion chamber. This is an inherently dirty—but extremely powerful—system, because a power stroke .
That's the promise of Achates Power, which has been working for a decade on its horizontally opposed two-stroke diesel truck engine. Now, it says, the company expects to announce its first pilot program with a global engine or vehicle maker within 18 That is about to change, with the latest split-cycle engines from the Scuderi Group offering greater fuel efficiency and up to 80 percent reduction in NO x emissions and 50 percent reduction in CO 2. Split-cycle engines feature paired cylinders Answer: Back in the early ’90s, when Ford had built a DFI two-stroke auto engine and were testing it, the company found that it could get its oil consumption down lower than that of four-stroke production car engines of the time. In fairness to the four NO new car marketed in the United States has been powered by a two-stroke engine since Saab phased out its hard-to-housebreak 3-cylinder in the late 1960s, when federal air pollution laws were taking hold. And with images from Eastern Europe of belching .
