In Japan, almost all cars are gasoline-powered, but as with everywhere else these days alternatives are slowly making their way into local markets.
To compete, Japanese automaker Mazda has taken a leap into “Clean Diesel” with a new engine.
Diesel-powered engines are heavy, slow, and more expensive than your typical gasoline-powered ones; however, they deliver improved fuel efficiency and, most of all, they don’t run on gas.
Instead, the engines use a mix of gas and super-heated compressed air to generate power. This is the strength of a diesel engine and Mazda looks like it’s set to develop an ideal, clean-running engine.
The first major hurdle with these new engines is finding a solution to diesel particulate matter, which in the promotional video below isn’t mentioned by the company.
The solution to this air-pollution has been to use filters in order to capture as much of the harmful particles as possible. One of the main pollutants from diesel engines is Nitrogen Oxide and unlike the microscopic particulate matter, it cannot be captured easily.
So the issue remains if Mazda is able to make an engine that functions well and is able to compete amongst Mercedes, BMW, and other Chinese and Korean brands that are developing clean technologies.
It also begs the question whether developing a “clean burning” diesel engine will compete against companies like Tesla that is developing electric cars that have zero emissions.
This new engine from Mazda is able to create the same amount of energy with less compression involved bringing down the pollutants released during the exhaust stroke. In other words, the new engine will be quieter, generate less pollution, and be more energy efficient.
Mazda’s goal seems to be making diesel powered cars the new alternative for Japanese drivers.
