The most prominent 4-rotor engine from Mazda, the R26B, was used only in various Mazda-built sports prototype cars including the 787B and the RX-792P in replacement of the older 13J. In 1991 the R26B-powered Mazda 787B became the first Japanese car and the first car with anything other than a reciprocating piston engine to win the 24 Hours of ...
Following the 1990 season, Mazda continued development of the 787 chassis in order to make improvements on its pace and reliability. One major development was the intake system for the rotary engine. In the past, Mazda had developed variable-length telescopic intake runners to optimize engine power and torque for varying RPM levels.
The 2008 Focus with the PZEV emissions package produces 132 hp (98 kW; 134 PS) at 6000 rpm and 133 lb⋅ft (180 N⋅m) of torque at 4250 rpm. [2] Mazda's LF-VD version was equipped with Direct Injection Spark Ignition (DISI) and a higher compression ratio for improved efficiency in the JDM and EDM markets. It produces 148 hp (110 kW; 150 PS) at ...
camshaft with Mazda's Multi-Function cam profile theory (increases valve lift to 9.1 mm (0.36 in) and enhances the engine's volumetric efficiency at lower speed range, resulting in an improved torque output, never falling below 108 N⋅m (80 lb⋅ft) between 1500 rpm and 4500 rpm)
The Mazda RX-8 is a sports car manufactured by Japanese automobile ... at 8,250 rpm and 159 lb⋅ft (216 N⋅m) of torque at 5,500 rpm with a 9,000 rpm (redline ...
The Mazda RX-7' is a front-engine, rear-wheel-drive, rotary engine-powered sports car, manufactured and marketed by Mazda from 1978 through 2002 across three generations, all of which incorporated use of a compact, lightweight Wankel rotary engine.
This effect optimizes volumetric efficiency over a given rpm range to provide maximum torque over the entire rpm range. VRIS is used on the K8, KF, and KL but nearly all modern Mazda V6s are now using this technology. The K-series all have a 7,000 rpm redline with 7500-7800 rpm limiter, which given the engine design is conservative.
The Mazda B series is a series of pickup trucks that was manufactured by Mazda. ... (55 kW) at 5,070 rpm and 92 lbf⋅ft (125 N⋅m) at 3,500 rpm. A four-speed manual ...
