It is more and more challenging for internal combustion engines in pick-up trucks which have heavy weight and high drag, to fulfill both strict fuel economy and emission regulations toward the target of “Carbon Neutrality”, while exceeding customer expectations. To overcome these difficult tasks, Toyota has developed the new 2.4L L4 turbocharged gasoline engine which for the first time complies with severe emission regulations such as Tier3 Bin30/LEVIII SULEV30 for body-on-frame midsize pick-up trucks. At the same time, both thermal-efficiency and maximum torque are improved by adopting high-speed combustion to the turbocharged engine based on the TNGA (Toyota New Global Architecture) platform, spray guide combustion by center direct injection in combustion chamber, quick light-off close-coupled three-way catalyst and a quick response turbocharger.
