Toyota launches several new engines that will be more economical than ever – thanks to a clever ploy that has previously only been available in hybrid models.
Over the next two years Toyota launches several new engines that will at least ten percent more economical than the engines they replace. Exactly which models the motors fall into is not clear, but 1,0 – and 1,3-liter engine is best suited for smaller models like the Yaris and Verso.
Toyota is shaken right now of a massive recall of 6.4 million vehicles that were sent out on Wednesday. In total, 27 models and here in Sweden hit 10,800 cars.
But Toyota also has good news to offer. Introducing a new generation of petrol engines that will at least ten percent more economical than the outgoing engines. Like any other automakers must Toyota in cutting fuel consumption and emissions. Therefore launched a 1.3-liter engine that has a faster combustion process and higher compression than before (13.5:1). The engine also uses Atkinsoncykeln, hitherto only existed in petrol engines as Toyota and Lexus used in hybrid models. Atkinsonmotorn has a different camshaft and can provide lower fuel consumption when the engine is running at partial load – ie when the driver does not give full throttle. A disadvantage Atkinsoncykeln is that the engine usually do not have as much effect as a conventional gasoline engine. There is no problem in hybrid cars where the electric motor provides an extra ‘boost’ when needed. But when the new Atkinsonmotorn now installed in cars that do not have hybrid drive must Toyota get around the problem by using higher compression. Atkinsonmotorn also has an intake port with a new form of vortex chamber, refrigerated recirculation of exhaust gases and an advanced valve timing system (VVT-iE, Variable Valve Timing-Intelligent Electric).The new engine is also as the basis for a variety of larger engines. They receive the same basic technology but add Toyota also to direct injection and supercharging with turbo. A total of 14 new engine variants to be launched in the next two years, and to be offered in 30 percent of all sold Toyota Models.
With the new engines, Toyota is at the forefront of engine development. Good work:
