The range Yaris will feature new block.
The range Yaris will have a new engine 1.5-liter 111 HP in replacing the current 1.3-liter gasoline. This new block comes in anticipation of the entry into force of the entry into force of the emission standard Euro 6c.
This new 4-cylinder engine is part of the family ESTEC ―Economy with Superior Thermal Efficient Combustion― and improves both performance and the consumption of the previous block of 1.3 liters.
1.496 c. c. and atmospheric, delivering 111 HP (82 kW) with a maximum torque of 136 Nm at 4400 rpm, of which, 118 Nm are now available at only 2,000 rpm. According to the japanese brand, the Yaris equipped with this engine is able to improve by up to 0.8 seconds for the mark of 0 to 100 km/h -11,0 seconds compared to 11.8— and in more than a second recovery of 80 to 120 km/h, for 17.6 seconds in front of the 18,8 that it took with the previous 1.3-liter.
the secret of The performance of this engine is in a higher thermal efficiency, which the firm stood at 38.5 per cent. To do this, it has a high compression ratio, encrypted 13.5, and adopting a system of exhaust gas recirculation (EGR) cooled and modifying the adjustment to the variable valve, so that the new engine of 1.5 liters is able to switch from Otto cycle to Atkinson cycle.
The new block is able to switch from Otto cycle to Atkinson.
The increase of the compression ratio is due to the redesign of the combustion chamber itself and the use of new pistons, optimizing the air-fuel mixture, which is now more homogeneous and allows you to burn faster.
In terms of the distribution, the new system timing variable intake valve, called VVT iE2, allows the engine to pass work on Otto cycle to Atkinson cycle according to the needs of the vehicle, switching is performed automatically in a fraction of a second. To this end we resort to a hydraulic system, in charge of shift of phase of the exhaust camshaft.
Another advance is the the liquid cooling of the exhaust manifold, avoiding the enrichment of the mixture is necessary to reduce the combustion temperature, so that reduce both consumption and emissions at any speed. While also incorporating all the advances in reduction of friction losses that incorporate the engines of the family ESTEC Toyota.
