Diesel engines are getting outdated day by day for a lot of reasons, majorly they will be drowned by the latest EV and Hybrid technologies. All the motor heads in the industry are working to create highly efficient Electric vehicles and Hybrid vehicles. And then there is Mazda motors, looking for a totally new future of gasoline engines. Diesel engines provide better fuel efficiency than gasoline engines but they also create more pollution. And pollution is something everyone is trying to counter. Meanwhile, Mazda is planning to introduce the first ever compression ignition gasoline engine by 2019, which will run for more distance in lesser fuel, means they are going to launch the ideal IC engine.
What are Compression Ignition Engines?
Compression ignition (CI) engines are basically powered by diesel fuel. In CI engines fuel burns without the spark, it only burns by high compression in the combustion chamber. When the piston goes up it compresses the air and then diesel fuel is added, after which a small explosion takes place. It generates enough power to push down the piston to rotate the crankshaft, the perfect procedure to generate power without a spark.
What are the plans of Mazda?
As we have explained the concept of CI engines, Mazda is going to take this concept but it will change the fuel, they will use gasoline in this. Gasoline powered engines need spark plugs to initiate a spark to create an explosion and generate power. Engineers have spent a lot of years trying to make this kind of technology but Mazda made it possible. Mazda’s new technology is christened as “Spark Control Compression Ignition”. It is Mazda’s version of the Homogeneous Charge Compression Ignition (HCCI) engine to burn gasoline in diesel style. Mazda will use leaner air-fuel charge in this technology which means less fuel as compared to air, its direct outcome would be the better mileage and also it will not compromise with the amount of power generated.
Problems in this new technology:
Spark Controlled Compress Ignition engine is a combination of two concepts, so it is obvious to face some problems. When we are not using a gasoline engine at initial stage but instead at higher RPM, a spark is must to ignite the fuel which is the first problem they have faced. But it seems like the issue is solved according to Mazda’s statement. Another big dilemma for the technology is auto-ignition or pre-ignition. After a certain time when the engine is heated up, fuel will get the ignition before its timing which would cause misfire and can lose power, but engineers are working out to solve the issue and soon it will be sorted. You all know by now that no matter how cool a misfire looks and sounds, it is something which is harmful for both engine and environment if not controlled.
Benefits over other engines:
As it is based on diesel engine, it will consume less fuel so it will give you more miles in less fuel and it is 20 to 30 percent more efficient than the current engines. It is coupled with a supercharger so it is estimated to generate 10 to 30 percent more torque. Thus making it a great combination of better mileage with better performance.
But we have to wait for two more years to see the ideal Internal Combustion engine coming to the automotive world. As we wait for Mazda’s new engine technology, we can only wonder if Mazda can pull this off. Although we all would agree that Mazda always comes with very interesting innovations, be it the Rotary-powered Hybrid technology or be it the Spark Controlled Compression Ignition engine. Mazda’s direction is something which not all would take, a road less traveled. But how fruitful would it be, as all the major manufacturers have shifted their focus on fuel-less vehicles and that is the inevitable future. Though until then, why not go wild for a while.
