The Nagumo F-series engine is a straight-six diesel engine designed and produced by Nagumo Heavy Industries Powertrain Division. It displaces 10.5litres and began production in 1991 as the NSL and NSLD (defense) at Nagumo Powertrain Plant 5 in Fushou.
The F-series engine is a road going version of the larger Nagumo E-series engine, which is typically utilized for heavy industrial use in generators, mining equipment and other heavy duty functions. The F-series is widely utilized in Jin Yi for heavy and medium duty applications such as buses, trucks, and other vehicles. The F-series production D is used specifically for defense applications and continually developed.
The F-series engines are available with multiple emissions packages to fulfill emissions requirements in various nation but the most common is the Schedule C emissions control package, which is required for certain areas of Jin Yi.
Models
FSL
- FSL Production A (FSL-PA) - 250 hp, 850 lb/ft
- FSL Production B (FSL-PB) - 260 hp, 1010 lb/ft
- FSL Production C (FSL-PC) - 350 hp, 1320 lb/ft
- FSL Production D (FSL-PD) - 500 hp, 1560 lb/ft
- FSL Production E (FSL-PE) - 750 hp, 1920 lb/ft
FSLD
The FSLD is a production variant for the defense industry released in 1992 for the ZZPT92155 "Haru" self-propelled gun. This early variant produced 650 Template:Horsepower and 1,050 pound force-feet of torque. Per Jin military specifications, it was a multifuel engine capable of burning diesel, gasoline, kerosene, and other types of common fuels. While the engine runs best on diesel, it has the ability to adjust injection timing and uses multifuel injectors to allow the engine to run on other fuels should it be necessary. Rather than diesel lubrication of the fuel pump and other key components, these components are lubricated oil, allowing the engine to run thinner fuels if necessary without issue. This also allows poor quality fuel to be mixed in and permits the engine to run on mixtures of different fuels if a unit is running low on supplies in the field. The engine comes with a grid heater on the intake standard, which heats the air coming into the intake during ignition to aid cold weather starts and is a standard feature on all Nagumo engines.
There are multiple power ranges and multiple packages available. A cold weather package adds a 1500w block heater and a 650w fuel tank heater, in addition to a heated fuel/water separator in order to aid the engine in starting in subzero winter temperatures. Additional insulation around the fuel lines, injectors, and fuel filters assist in heat retention. For engines that have an auxiliary power unit that can run separate from the engine, all of the cold weather heating functions can be run independently of the engine, keeping the engine warm for rapid starts. All cold weather package engines can also be ordered without provisions for climate control, such as no air conditioning compressor, since those would both need to be electric in order to function with the engine turned off.
Models
- FSLD Production A (FSL-PA) - 650 hp, 1050 lb/ft
- FSLD Production B (FSL-PB) - 750 hp, 1300 lb/ft
- FSLD Production C (FSL-PC) - 860 hp, 1550 lb/ft
- FSLD Production D (FSL-PD) - 1,010 hp, 1400 lb/ft
- FSLD Production E (FSL-PE) - 1200 hp, 2010 lb/ft
- FSLD Production F (FSL-PF) - 1500 hp, 2200 lb/ft
Export models
FSLD Production G (FSL-PG)
Production variant for Arcadie tuned to 1300 hp and 1700 lb/ft of torque. The G was shipped without provisions for an air conditioning compressor or heater core in the cooling system since the engine was designed to be paired with an auxiliary power unit aboard typical military vehicles. Shipped with provisions for mounting a condenser in front of the radiator for easier integration.
