The L is the first L engine produced. Toyota solely refers to it as the L engine, not the 1L engine. 2.2 L (2,188 cc), four-cylinder diesel engine.[7] Bore and stroke are 90 mm × 86 mm (3.54 in × 3.39 in), with compression ratios of around 21.5:1[8]
Applications:
72 PS (53 kW; 71 hp) at 4200 rpm, 14.5 kg⋅m (142 N⋅m; 105 lb⋅ft) at 2400 rpm (Gross JIS)
The 2L is a 2.4 L (2,446 cc) 4-cylinder diesel engine. Bore and stroke are 92 mm × 92 mm (3.62 in × 3.62 in), with compression ratios of around 22.3:1 and a redline of 4800 rpm. Outputs range from 76 to 87 PS (56 to 64 kW; 75 to 86 hp) and torque of 15.8–16.8 kg⋅m (155–165 N⋅m; 114–122 lb⋅ft).
Applications:
83 PS (61 kW; 82 hp) at 4200 rpm, 17 kg⋅m (167 N⋅m; 123 lb⋅ft) at 2400 rpm (JIS Gross)
The 2L-II is an upgrade of the 2L introduced simultaneously with the 3L engine in 1988 in the 5th generation Hilux.[36] Although bore and stroke remain the same, multiple changes have been made in its design. 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. The exhaust valve is 1mm larger in diameter and the inlet manifold is made 10mm larger in diameter.[37] The pistons with a 5mm shorter compression height and piston rings were placed closer to the combustion chamber to reduce wasted volumetric capacity while durability was improved by the adoption of fiber reinforced piston grooves from the 1st Generation 2LTE to improve piston ring seizure resistance, groove wear resistance, thermal conductivity and thermal fatigue resistance over the previous Ni-Resist cast iron insert used previously to address ring seizure issues and wear resistance in bare aluminum pistons while the oil squirters were relocated to spray underneath the hottest part of the piston to further aid cooling.[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.[37] The valve clearance is adjusted using shims. Later L engines (3L and 5L) also use this method of valve operation.[36]

2L-T
Early 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. A dual mass flywheel was introduced in 1985 and pilot fuel injection in 1988.[58]
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)
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 varies with fitment. Output is 94 PS (69 kW; 93 hp) at 4000 rpm, 22 kg⋅m (216 N⋅m; 159 lb⋅ft) at 2400 rpm.[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
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. Although electronic fuel injection systems had long been used in gasoline engines, this is among the first diesel engine to adopt such a system.[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. 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.[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. 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.[59] The 2L-TE was largely replaced by the KZ engine in 1993, although it continued to be used in some models until 2000.[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). Compression ratio is also increased to 21.0:1, slightly higher than the 2L-T and 2L-TE. Maximum horsepower is 97 PS (71 kW; 96 hp) at 3800rpm and maximum torque ranges from 22.5 kg⋅m (221 N⋅m; 163 lb⋅ft) to 24.5 kg⋅m (240 N⋅m; 177 lb⋅ft) at 2400rpm.
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)
Introduced in 1984, the High Pressure turbocharged version of 2L-TE features ceramic chambers.[58] In this engine, 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 however compression is increased to 21:1.[88] The 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).[88] The engine comes with a Turbo charger and used the EFI (Electronic Fuel Injection) system as well. Ignition feedback control would be added in 1985.[58]
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)
94 PS (69 kW; 93 hp) at 4000 rpm, 20.5 kg⋅m (201 N⋅m; 148 lb⋅ft) at 2400 rpm (Net, Japan)
Has the same dimensions and is still referred to as the 2L-THE 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.[citation needed][clarification needed]
The 3L is a 2.8 L (2,779 cc) four-cylinder diesel engine. The bore and stroke of this engine is 96 mm × 96 mm (3.78 in × 3.78 in), and the compression ratio of 22.2:1.[71]
The 5L is a 3.0 L (2,985 cc) four-cylinder diesel engine. Bore and stroke is 99.5 mm × 96 mm (3.92 in × 3.78 in), with a compression ratio of 22.2:1.[98]
The 5L-E is a 3.0 L (2,985 cc) EFI version of the 5L engine. It is the latest member of the L family. It has a bore and stroke of 99.5 mm × 96 mm (3.92 in × 3.78 in), with a compression ratio of 22.2:1. Output (as fitted to the Hilux) is 78 kW (106 PS; 105 hp) gross at 4200 rpm with 20.1 kg⋅m (197 N⋅m; 145 lb⋅ft) gross of torque at 2200 rpm.[112] Power output varies according to fitment. The engine number is found on the top face of the block at the front of the engine.
