The Nissan TD engine was a series of diesel engines manufactured by Nissan. All TD-series engines are indirect injection, swirl chamber diesel units with cast iron blocks and heads; most versions are four-cylinders aside from the six-cylinder TD42.[1] The head is a pushrod-operated, overhead valve, crossflow design with two valves per cylinder.[2] Of a simple, somewhat old-fashioned construction, the engines are generally durable if not very powerful.[1][3][4] Rather than driving the camshaft with the typical chain or belt, the TD-series engine uses direct gears.[1]
The TD23 measures 2.3 L (2,289 cc) with a swirl chamber.[5] The bore and stroke are 89 mm × 92 mm (3.50 in × 3.62 in) and the engine has a 22.0:1 compression ratio. It is the least common of the TD series engines, and ended production around 1995.[5][6]
This engine was installed in the 1987-1992 Nissan Pickup (D21); it was also used in the 1986-1988 E24 series Nissan Caravan.[6] It replaced the earlier SD23 engine in Nissan Atlas 1-ton trucks in 1986.[8]
The TD25's bore and stroke are 93 mm × 92 mm (3.66 in × 3.62 in), giving 2.5 L (2,494 cc). Period reviewers referred to the unit as "thoroughly viceless" and "a bit bland".[3] This engine was also used by JASO, the Japanese Automotive Standards Organization, for their diesel oil Detergency Test procedure (M 336:1998) from 1998 until engine assemblies and parts became unavailable in 2009.[9][10]
It is applied to the following vehicle(s):
It has been used in the 1990–present Nissan Cedric YPY31, the Nissan Navara D21 series, and the 1-ton Nissan Atlas F23 series from 1995 to 1999 (sold as the Cabstar in Europe and certain other export markets). It was also used in the Nissan Caravan/Urvan (E24).[3]
Bore and stroke are 96 mm × 92 mm (3.78 in × 3.62 in) giving 2.7 L (2,663 cc); as is typical for the TD series it features a swirl combustion chamber. Maximum power of the naturally aspirated model is 85 PS JIS (63 kW; 84 hp) at 4,300 rpm.[12] A turbocharged version of the TD27 was introduced in 1988. The low-stressed naturally aspirated engine has a strong reputation for reliability, with engines regularly reaching half a million miles.[4] The General Secretary of Britain's Licensed Taxi Drivers' Association (LTDA) referred to the TD27 as "one of the greatest engines ever put in a cab."[13]
This engine was also exported to the United Kingdom and fitted to LTI's Fairway series, coupled to manual or automatic transmissions also supplied by Nissan.[14] It was chosen after extensive testing by engineering consultants Ricardo PLC. The company offset the cost of importing engines from Japan by Nissan agreeing to sell 200 Fairways in Japan every year under the "Big Ben" name.[2] The TD27 continued to be installed on the succeeding TX1 series.[13]
The TD27 was mainly fitted to a number of Nissan light duty commercial vehicles and was used as the most common diesel option in Nissan Homy, Caravan, and Urvan vans. Along with the TD23 and TD25, it was also fitted to the D21 series Datsun Truck (also known as Nissan Pickup, Navara, etcetera). The turbocharged versions were also fitted to the Nissan Caravan and its various rebadgings, to the Nissan/Datsun Pickup, the Nissan Terrano SUV (D21 as well as the succeeding R50), and to the Nissan Terrano II (R20; sold as the Mistral in Japan).
The power range of the regular turbocharged versions (TD27T; built from 1985 until 2007) range from 100–115 PS (74–85 kW; 99–113 bhp) depending on fitment; when fitted with an intercooler (TD27Ti) power increases to 125 PS (92 kW; 123 bhp).[15] The most powerful TD27ETi model, introduced in 1995 and built until 2001, is intercooled and has an electronically controlled high pressure fuel pump, called "electronically controlled fuel injection" by Nissan at the time.[16]
The TD42 measures 4169 cc; it's a square engine and the bore and stroke are 96 mm × 96 mm (3.78 in × 3.78 in). It is a naturally aspirated six-cylinder diesel engine with mechanically controlled fuel pump. Early models have a black cylinder head cover ("Blacktop"), while later models are silver ("Silvertop").[1] Since 1988, Nissan Diesel Industrial Engines also manufactured this model for use in forklifts; the company building these (and the industrial versions of the TD25/TD27) changed name to Nissan Industrial Engine Manufacturing (NIEM) in 1995 and became Global Component Technologies (GCT) in 2015 - at which point the TD-series engines remained in production for forklift use.[17] Old-fashioned but generally durable, the TD42 is not particularly fuel efficient and may be sensitive to receiving proper cooling.[1]
The naturally aspirated versions of the TD42 produce from 115 to 135 PS (85 to 99 kW; 113 to 133 bhp) depending on market, fitment, and measuring methods. It has been installed in the Nissan Civilian series (W40, W41) and the Nissan Safari/Patrol (Y60/61).
A series of turbocharged versions have been available since 1993. These have also been fitted with an intercooler (TD42Ti). Introduced in 2003 this version received electronic control of the injector-pump timing - a basic system that controls the fuel pump, while retaining the mechanically driven fuel injectors of the previous engines.[1] The electronic control version was called the TD42ETi by Nissan.[18] It has increased torque while also allowing the car to meet new, stricter emissions standards. Power outputs of the turbocharged models range from 145 to 160 PS (107 to 118 kW; 143 to 158 bhp) depending on fitment, model, and market.
