TheL family is a family ofinline four-cylinderdiesel engines manufactured byToyota, which first appeared in October 1977. It is the firstdiesel engine from Toyota to use a rubbertiming belt in conjunction with aSOHC head. Some engines[which?] like the 2L-II and the 2L-T are still in production to the present day. As of August 2020[update], the 5L-E engine is still used in Gibraltar in the fifth-generationToyota HiAce, eighth-generationToyota Hilux, second-generationToyota Fortuner, and fourth-generationToyota Land Cruiser Prado.[2][3][4][5] Vehicles with the diesel engine were exclusive to Toyota Japan dealership locations calledToyota Diesel Store until that sales channel was disbanded in 1988.[6]
TheL 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), withcompression 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)
The2L 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), withcompression 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).

The2L-II is an upgrade of the 2L introduced simultaneously with the 3L engine in 1988 in the 5th generation Hilux.[36] Althoughbore andstroke remain the same, multiple changes have been made in its design. Theengine block was made more rigid through the use offinite element analysis and through adding reinforcement ribbing.[37] The most significant change is the redesignedcylinder head, where the camshaft now lifts the valve directly via tappet instead of using a rocker arm. Theexhaust valve is 1mm larger in diameter and theinlet manifold is made 10mm larger in diameter.[37] Thepistons 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 improvepiston ring seizure resistance, groove wear resistance, thermal conductivity and thermal fatigue resistance over the previousNi-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 thecompression 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]

The2L-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]

Developed as a new version of 2L-T in 1982,[58] the2L-TE featured a new development used in diesel engines at that time, anelectronically 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 ofmetal 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. Theredline of this engine is at 4800 rpm, the compression ratio is 20.0:1.[65] The 2L-TE was largely replaced by theKZ 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)
The2L-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 maximumtorque 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.

Introduced in 1984, the High Pressure turbocharged version of2L-TE features ceramic pre-combustion 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 maximumtorque was 20.5–22.5 kg⋅m (201–221 N⋅m; 148–163 lb⋅ft).[88] The engine comes with aTurbo 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)
