In developing our next-generation 2.0L diesel engine, we aimed at emissions performance to meet global standards and fuel economy raised by as much as 10%. We are also pursuing the kind of performance that allows stress-free driving up to high engine speeds. To fulfil our aims, we are promoting direct piezo-injection technology enabling multi-stage injection, reduction of the weight and size of every reciprocating and rotating component as well as the aluminum cylinder block. A two-stage turbocharger is adopted to yield both high torque in the low rev range and an increased acceleration response. The most advanced catalyst technologies, such as a highly efficient catalyst to burn particulate matter, are also fitted.
Next Generation RENESIS (Rotary Engine 16X)
In developing the next-generation RENESIS, Mazda made a thoroughgoing revision of engine dimensions including the trochoid rotor housing, adopting a longer stroke and larger displacement of 1600cc (800cc x 2) aimed to raise thermal efficiency and boost torque at all engine speeds. By employing the Hydrogen RE design policy of a direct injection system and aluminum side housing, as well as various other measures, we are further promoting the rotary engine’s merits of light weight and compact size.
SISS (Smart Idle Stop System)
Mazda’s SISS restarts the engine without using an electric motor. The system injects fuel directly into the cylinders while the engine is stationary and ignites the fuel to create downward piston force that serves to start the engine, resulting in fuel savings of about 10% in Japan’s 10-15 mode in addition to restarting the engine quickly and quietly.
Rear Vehicle Monitoring System
Radar sensors in the left and right rear corners of the body detect a vehicle approaching from the rear or in the blind area behind the B-pillars. The system is active when traveling at 60 km/h or faster.
