It is the first diesel engine from Toyota to use a rubber timing belt in conjunction with a SOHC head.

The engine block was made more rigid through the use of finite element analysis and through adding reinforcement ribbing.

[37] The most significant change is the redesigned cylinder head, where the camshaft now lifts the valve directly via tappet instead of using a rocker arm.

[38][37][clarification needed] The revised pistons were 100g lighter than the ones in the 1st Generation 2L and the compression ratio changed to 22.2.

The 2L-T(II) is an upgrade of the 2L-T. Of the same dimensions as all other 2L engines, the most significant change is that the camshaft lifts the valve directly via tappet instead of a rocker arm.

[70] Applications: Compression Ratio 20.0:1 91 PS (67 kW; 90 hp) at 3500 rpm, 23.1 kg⋅m (227 N⋅m; 167 lb⋅ft) at 2200 rpm (UK)1997-2000 Compression Ratio 21.0:1 94 PS (69 kW; 93 hp) at 4000 rpm, 22.0 kg⋅m (216 N⋅m; 159 lb⋅ft) at 2400 rpm (Net JIS) 90 PS (66 kW; 89 hp) at 4000rpm, 22.3 kg⋅m (219 N⋅m; 161 lb⋅ft) at 2200rpm (UK)2000 onwards Compression Ratio 22.2:1 90 PS (66 kW; 89 hp) at 3500rpm, 22.2 kg⋅m (218 N⋅m; 161 lb⋅ft) at 2250rpm (UK, DIN) Developed as a new version of 2L-T in 1982,[58] the 2L-TE featured a new development used in diesel engines at that time, an electronically controlled injection pump.

[citation needed] The electronic system (called "EFI" by Toyota) meters fuel with great precision and increased the engine's efficiency.

It works through a combination of multiple sensors similar to those in a gasoline engine, but rather than actuating a fuel injector it actuates an SPV (Spill Control Valve) which is located on the head of the injection pump.

[73][58][74] Like the 2L-T, it is a turbocharged 2.4 L (2,446 cc) SOHC (single overhead cam) engine with 8 valves.

[citation needed] Applications: 96 PS (71 kW; 95 hp) at 4000rpm, 19.5 kg⋅m (191 N⋅m; 141 lb⋅ft) at 2400rpm (Gross JIS) The 2L-TE(II) is an upgrade of the 2L-TE.

Of the same dimensions as the 2L-TE engine, the most significant change is that the camshaft lifts the valve directly via tappet instead of a rocker arm.

The valve clearance is adjusted using shims (the earlier heads were prone to cracking under high temperatures because of a cooling chamber that runs between the intake and exhaust valves and allows for steam build up at high temperature - part number 11101-54120, that was fixed in the later 2nd gen heads - part number 11101-54121).

[88] The engine comes with a Turbo charger and used the EFI (Electronic Fuel Injection) system as well.
