Toyota L engine

The L family is an engine family manufactured by Toyota. It first appeared in October 1977 and is a series of inline four-cylinder diesel engines. It is the first diesel engine from Toyota to use a rubber timing belt in conjunction with a SOHC head. Engines like 2L-II and 2L-T are still in production to the present day. As of August 2020, the 5L-E engine is still used in Gibraltar in the fifth-generation Toyota HiAce, eighth-generation Toyota Hilux, and second-generation Toyota Fortuner.[2][3][4] Vehicles with the diesel engine were exclusive to Toyota Japan dealership locations called Toyota Diesel Store until that sales channel was disbanded in 1988.[5]

Chronology
SuccessorToyota KD engine

L

The L is the first L engine produced. Note that Toyota just calls it the L engine, not the 1L engine. 2.2 L (2,188 cc), four-cylinder diesel engine.

Applications:

2L-II
2L-II engine in Toyota Hilux

The 2L-II is an upgrade of the 2L. Bore and stroke remains the same. 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. Later L engines (3L and 5L) also use this method of valve operation.

Applications:


73 PS (54 kW; 72 hp) at 4000 rpm, 15.2 kg⋅m (149 N⋅m; 110 lb⋅ft) at 2400 rpm (Net JIS)

2L-T

The 2L-T is a 2.4 L (2,446 cc) turbo version of the 2L still being produced since 1982. The bore and stroke are the same but the 2L-T has a compression ratio of 20:1. Output is 85 to 91 PS (63 to 67 kW; 84 to 90 hp) gross at 4000 rpm with 19.2 kg⋅m (188 N⋅m; 139 lb⋅ft) gross of torque at 2200 rpm.

2L-T(II)

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. The valve clearance is adjusted using shims. Compression rate is also 20:1. Output is 94 PS (69 kW; 93 hp) at 4000 rpm, 22 kg⋅m (216 N⋅m; 159 lb⋅ft) at 2400 rpm.[54]

2L-TE
Toyota 2L-TE engine from 1982

Developed as a new version of 2L-T in 1982,[41] the 2L-TE featured a new development used in diesel engines at that time, the EFI (Electronic Fuel Injection) system. Although such systems had long been used in gasoline engines, this is among the first diesel engine to adopt such a system. Although the basic construction is similar to a modern gasoline injector, the EFI system in 2L-TE utilizes considerably higher injection pressures. The EFI system meters fuel with great precision and increased the engine's efficiency. To improve durability a new piston design using alumina-silica ceramic fiber reinforced piston ring grooves was used in place of the usual cast iron insert. This makes it one of the earliest applications of metal matrix composites.[58][41][59] Like the 2L-T, it is a turbocharged 2.4 L (2,446 cc) SOHC (single overhead cam) engine with 8 valves (the earlier heads were prone to cracking under high temperatures because there is a cooling chamber that runs between the intake and exhaust valves and it allows for steam build up - part number 11101-54120, that was fixed in the later 2nd gen heads - part number 11101-54121). The bore and stroke is 92 mm × 92 mm (3.62 in × 3.62 in). Due to the EFI system, the 2L-TE develops significantly more torque than its predecessor. The redline of this engine is at 4800 rpm, the compression ratio is 20.0:1.[42] The 2L-TE was largely replaced by the KZ engine in 1993, although it continued to be used in some models until 2000.

Applications:


96 PS (71 kW; 95 hp) at 4000 rpm, 19.5 kg⋅m (191 N⋅m; 141 lb⋅ft) at 2400 rpm (Gross JIS)

2L-TE(II)

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. Compression rate is also increased to 21:1, slightly higher than the 2L-T and 2L-TE. Maximum horsepower is 97 PS (71 kW; 96 hp) at 3800 rpm and maximum torque is 22.5 kg⋅m (221 N⋅m; 163 lb⋅ft) at 2400 rpm.

Applications:

97 PS (71 kW; 96 hp) at 3800 rpm, 22.5 kg⋅m (221 N⋅m; 163 lb⋅ft) at 2400 rpm (Net JIS)


94 PS (69 kW; 93 hp) at 4000 rpm, 22.0 kg⋅m (216 N⋅m; 159 lb⋅ft) at 2400 rpm (Net JIS)


97 PS (71 kW; 96 hp) at 3800 rpm, 24.5 kg⋅m (240 N⋅m; 177 lb⋅ft) at 2400 rpm (Net JIS)

2L-THE

Introduced in 1984, the High Pressure turbocharged version of 2L-TE features ceramic chambers.[41] The fuel is injected with a high pressure system. Bore and stroke remains the same, 92 mm × 92 mm (3.62 in × 3.62 in) for both. Maximum output was 94–105 PS (69–77 kW; 93–104 hp) at 4000 rpm and maximum torque was 20.5–22.5 kg⋅m (201–221 N⋅m; 148–163 lb⋅ft). Comes with a Turbo charger and used the EFI (Electronic Fuel Injection) system as well. Ignition feedback control would be added in 1985.[41]

Applications:

105 PS (77 kW; 104 hp) at 4000 rpm, 21.5 kg⋅m (211 N⋅m; 156 lb⋅ft) at 2400 rpm (Gross, Japan)
