Toyota TR engine


The Toyota TR engine is a family of DOHC 16-valve petrol engines produced by Toyota, started in July 2003. These engines are primarily used in medium-sized passenger and commercial vehicles with body-on-frame platforms. They are designed for longitudinal mounting in both rear-wheel drive and four-wheel drive applications. Every engine in the TR series is a square engine, meaning the bore diameter and stroke length are equal.
In January 2015, the TR engines were updated with Dual VVT-i technology, identifiable by the additional VVT-i solenoid on the top of the cylinder head cover. However, the original single VVT-i configuration remains in production for specific vehicle models.

1TR-FE

The 1TR-FE is a version of the TR engine. Bore and stroke are, and the compression ratio is 9.8:1. Its power is at 5,600 rpm, and of torque at 4,000 rpm with a redline of 6000 rpm.
In January 2015, the 1TR-FE engine was updated with Dual VVT-i technology and a higher 10.4:1 compression ratio. The updated power is at 5,600 rpm and of torque at 4,000 rpm.

Applications

1TR-FPE

The 1TR-FPE is an LPG version of the 1TR-FE engine with a higher 10.6:1 compression ratio. Initially, it produced at 4,800 rpm and torque is at 3,600 rpm. In 2010, the output was revised to produce at 4,800 rpm and torque is at 3,600 rpm. Unlike the regular 1TR-FE engine, this engine was never updated with Dual VVT-i technology.

Applications

2TR-FE

The 2TR-FE is a version of the TR engine. The bore and stroke are, and the compression ratio is 9.6:1. Maximum power is at 4,800–5,200 rpm, and of torque at 3,800 rpm with redline of 5,500 rpm. Average fuel consumption using the JC08 method is.
Like the smaller 1TR-FE, the 2TR-FE was also received updates in January 2015 to feature Dual VVT-i and a higher 10.2:1 compression ratio. The maximum power with Dual VVT-i is at 5,200 rpm, and of torque at 3,800–4,000 rpm.
There was also a version of 2TR-FE engine made by FAW Toyota called 3TR-FE, exclusively for the Chinese market Toyota Coaster B50 from 2013 to 2019. Unlike the 2TR-FE, the 3TR-FE was never updated with the Dual VVT-i technology.
