Mazda turns to diesel power

When you think about diesel engine, Mazda is not exactly the name of the company that comes to mind. But in fact, Mazda has been producing diesel power since 1982, making his first appearance in the 626 - but not in Canada.

Recently, Mazda has unveiled its new SKYACTIV D engine that will come to Canada in the summer of 2012, according to Mazda, the new Mazda6 and CX-7.

A closer look at the new Mazda SKYACTIV D shows some real differences compared to current diesel models.

For example, the new D SKYACTIV meets Tier 2 Bin 5 standards without the help of an "after treatment" as some of today's diesel engines to whom he cans Urea job that must be completed as part of regular maintenance program .

What Mazda did not concentrate on the timing of combustion and the loss of mechanical energy. D SKYACTIV features the lowest compression ratio available in a diesel at 14h01. By comparison, the Volkswagen TDI is 16.5 to 1 and others can be as high as 18:1.A lower compression ratio is ideal, but it has had to overcome challenges Mazda. The main issues are hit and cold starts, including failures.

Mark Whitehead: When a diesel engine is cold, the glow plugs are the first thing that needs work. They must be able to get very hot and survive in a corrosive environment of the engine for its entire life without compromising performance. And, because drivers want diesel economy, but will not tolerate poor performance of cold start, today's systems is expected to start the engine faster. When direct injection diesel systems were introduced, they have presented new challenges for package: engine designers needed to place the injector in the middle and the glow plug needed to leave the runway.Today, most are direct-injection diesel and industry is relatively comfortable with the solutions. As diesel engines develop direct injection and cylinder pressures are up from 180bar 230bar in some applications. To produce warm-up time even shorter, you can add other heating coils and control that can produce very little warm-up time, but is it the solution for everyone?
