Learning Objectives Upon completion of Lesson Two, you should be able to: § Define the differences in a hybrid vehicle internal combustion engine. § Identify hybrid vehicle internal combustion engine service precautions. The Prius Toyota uses a 1.5 liter inline 4-cylinder engine (Figure 2-26) with VVT-i (Variable Valve Timing with intelligence) and ETCS-i (Electric Throttle Control System with intelligence). The engine includes a number of modifications that help balance performance, fuel economy and clean emissions in hybrid electric vehicles. One unique aspect of the 1NZ-FXE is its Atkinson cycle valve timing, which allows the engine to decrease emissions by varying the relationship between the compression stroke and the expansion stroke. Another feature incorporated on ’04 & later models is a special coolant heat storage system that recovers hot coolant from the engine and stores it in an insulated tank where it stays hot for up to three days. Later, an electric pump precirculates the hot coolant through the engine to reduce HC emissions normally associated with a cold start.
CVT • CVT allows for the operation at the lowest possible speed and highest possible load, partially avoiding the low efficiency region of the engine map. • A continuously variable transmission (CVT) transfers power through a range of speed/torque ratios from engine input to output, continuously without interruption • Contrast with either manual or conventional automatic transmissions that use discrete ratios and normally disengage when changing ratio • The CVT category includes infinitely variable transmissions (IVT) that give a zero output speed within the operating range
