1N
The 1N is a 1.5 L (1,500 cc) inline-four diesel engine. It utilizes a single overhead camshaft (SOHC) configuration with two valves per cylinder.
The engine's internal dimensions feature a bore of 74 mm (2.9 in) and a stroke of 84.5 mm (3.33 in), resulting in a compression ratio of 22:1. In terms of performance, the naturally aspirated 1N produces a peak power output of 55 PS (40 kW; 54 hp) at 5,200 rpm. Torque output ranges from 9.1 kg⋅m (89 N⋅m; 66 lb⋅ft) to 9.3 kg⋅m (91 N⋅m; 67 lb⋅ft), depending on the specific vehicle application.
Applications
- 55 PS (40 kW; 54 hp) at 5,200 rpm, 9.3 kg⋅m (91 N⋅m; 67 lb⋅ft) at 3,000 rpm (Net):
- 3rd and 4th Generation Toyota Starlet (NP70/80)[1][2][3][4]
- 55 PS (40 kW; 54 hp) at 5,200 rpm, 9.1 kg⋅m (89 N⋅m; 66 lb⋅ft) at 2,600 rpm (Net):
- 5th Generation Toyota Starlet (NP90)[5]
1N-T
The 1N-T is the turbocharged variant of the 1.5 L diesel engine. While sharing the same bore and stroke (74 mm and 84.5 mm) and 22:1 compression ratio as the standard 1N, the addition of forced induction increases performance significantly.
The 1N-T generates a peak power output of 67 PS (49 kW; 66 hp). Torque is also improved, ranging between 13.3 kg⋅m (130 N⋅m; 96 lb⋅ft) and 14.0 kg⋅m (137 N⋅m; 101 lb⋅ft), providing greater pulling power for the vehicles it powers.
Applications
- 67 PS (49 kW; 66 hp) at 4,700 rpm, 13.3 kg⋅m (130 N⋅m; 96 lb⋅ft) at 2,600 rpm (Net):
- 2nd Generation Toyota Corolla II / Toyota Corsa / Toyota Tercel (NL30)[6]
- 67 PS (49 kW; 66 hp) at 4,500 rpm, 14.0 kg⋅m (137 N⋅m; 101 lb⋅ft) at 2,600 rpm (Net):
- 3rd Generation Toyota Corolla II / Toyota Corsa / Toyota Tercel (NL40)[7][8][9]
- 67 PS (49 kW; 66 hp) at 4,200 rpm, 14.0 kg⋅m (137 N⋅m; 101 lb⋅ft) at 2,600 rpm (Net):
- 4th Generation Toyota Corolla II / Toyota Corsa / Toyota Tercel (NL50)[10]
