What do you imagine when heard about 2-stroke engines? Toned? Gasoline wasteful? Oil wasteful? Smoky? High emissions? Yes, because they are not efficient in fuel consumption and bad emission levels, and now 2-stroke engines slowly disappearing from the automotive world.
But for Renault, 2-stroke engines still make them curious to explore further the potential of this machine. In 2014, Renault had already made a very unique prototype of two-stroke diesel engine. Why unique? Just look at the specifications, 730 cc, two-stroke, two-cylinder engine with an additional turbo and supercharger.

When the usual diesel engine construction is already complicated, remember, this 2-stroke diesel engine with more faster combustion process. Not to mention the presence of a turbo and supercharger as well as to increase the number of its components. Yes, this machine is quite unique in our eyes.
Maybe it would be more comforting if we talk capabilities of these machines. This eccentric diesel engine can generate the power of 47 to 68 hp. Little too huh? But remember, this diesel engine, which should be to know is its torque ability.
The result itself is not bad, this machine can produce a torque of 112 Nm to 145 Nm and is available from 1,500 rpm of rotation. Renault also claimed that the machine will has sound like a modern 4-cylinder diesel engine in general.
With the power and torque capabilities, we may predict that this machine will inhabit the engine bay of a compact city car or hatchback. Better not to speculate too early, because in the eyes of the Renault, this engine is still too weak so it is not suitable to be installed in any of their car. This machine is made only to the exploration potential alone. *** [EKA | FROM VARIOUS SOURCES | CARSCOOPS]
