It was first introduced in the Camry in December 2014 for the Chinese market and March 2015 for the Thai market. It can work in the Otto cycle and a modified-Atkinson cycle depending on output power. Thermal efficiency is about 38. It was first introduced in the Camry in October 2018 for the Thai market. Maximum output when used in the Camry hybrid is 154 hp with 153 lb·ft of torque which doesn't include the additional power of the electric motor that is used in the Camry Hybrid. The stroke and bore are 86 mm × 86 mm. The Tumble control valves, along with new 12-hole high atomizing long-nozzle fuel injectors, reduce the amount of fuel adhering to the intake ports and therefore maximize fuel economy and reduce harmful emissions.
The forged steel crankshaft is fully balanced with eight counterweights and supported by five main bearings. New tumble control valves enhances combustion while the engine is cold, and helps to bring the catalytic converters up to working temperature quickly. The engine service mass is 324 lb 147 kg that includes the oil and coolant fully filled. Geometrical compression ratio is 12. . The cylinder block is an open-deck, midi-skirt type with cast-in iron liners and a die-cast aluminium lower crankcase and a stamped oil pan.
Power output in some applications, e. An Acoustic Control Induction System switches the length of the intake tract in two stages, based on rpm and throttle angle, thereby ensuring strong torque across a broad engine speed range. A helical gear pressed in No. This engine also replaced the in the U. It can work in the Otto cycle and a modified-Atkinson cycle depending on output power. .
