A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand how ...
Diesel’s on the outs in Europe, and EVs aren’t ready for prime time. Skyactiv-X seems, at this juncture, a hedge bet against both aspects. EV infrastructure lags massively behind our petroleum ...
A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...
SAE Transactions, Vol. 96, Section 4: RECIPROCATING ENGINES–SPARK IGNITION AND DIESEL (1987), pp. 614-623 (10 pages) A single-cylinder, variable–compression ratio, direct–injection diesel engine was ...
Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...
As Mazda and Infiniti have proved, there's a lot of innovation left in the internal-combustion engine. One of the more wild concepts we've seen is called Reactivity Controlled Compression Ignition ...
Skyactiv-X, Mazda’s newest engine, will use a compression ignition system to make its gasoline-powered vehicles more powerful and more fuel efficient than ever before. This innovative engine is at the ...
You own a diesel-powered vehicle and are thinking of giving it a tuneup. But does your diesel even have spark plugs to change? The short answer is no, diesel engines do not have spark plugs. Instead, ...
Car manufacturers are delving deep into their boxes of tricks to make internal combustion engines more efficient. Infiniti unveiled a variable compression ratio engine last year, and hybrid technology ...
