Chronology
Predecessor Nissan SD engine
Successor Nissan QD engine
Nissan ZD engine

The Nissan TD series is a series of diesel engines manufactured by Nissan. All TD-series engines are inline engines; most versions are four-cylinders aside from the six-cylinder TD42. They have cast iron blocks and crossflow heads; the combustion chamber design is a swirl-chamber design with indirect injection and a gear driven cam. [1] The valves are pushrod-actuated, and the engine has two valves per cylinder; [2] the camshaft is driven by a set of gears. [1] Of a simple, somewhat old-fashioned construction, the engines are generally durable if not very powerful. [1] [3] [4]

Straight-four

TD23

The TD23 has a bore and stroke of 89 mm × 92 mm (3.50 in × 3.62 in) and thus displaces 2,289 cc (139.7 cu in). [5] Its compression ratio is 22.0:1. It is the least common of the TD series engines, and ended production around 1995. [5] [6]

Outputs [7]

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]

TD25

The TD25's bore and stroke are 93 mm × 92 mm (3.66 in × 3.62 in), giving 2,494 cc (152.2 cu in). 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]

TD27

Bore and stroke are 96 mm × 92 mm (3.78 in × 3.62 in) giving 2,663 cc (162.5 cu in). 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. [4] A low output version of this engine intended for forklift use, producing 38 kW (52 PS) at 2,300 rpm, remained in production with GCT (Global Component Technologies, successor company to Nissan Diesel Industrial Engines) as of 2024. [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] The low-stressed naturally aspirated engine has a strong reputation for reliability. [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." [15] 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. [15]

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). [16] The most powerful TD27ETi model, introduced in 1995 and built until 2001, is intercooled, and has an electronically controlled distributor-type fuel injection pump. The system was called "electronically controlled fuel injection" by Nissan at the time. [17]

Straight-six

TD42

The TD42 has been in production since July 1987. It displaces 4,169 cc (254.4 cu in); it's a square engine and the bore and stroke are 96 mm × 96 mm (3.78 in × 3.78 in). Its fuel-injection pump is mechanically controlled. Early models have a silver cylinder head cover ("Silvertop"), while turbocharged TD42s and naturally aspirated ones built after 1995 are black ("Blacktop"). [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. [18] This low output version produces 61 kW (83 PS) at 2,400 rpm and was still in production as of 2024. [19] Old-fashioned but beloved for its ruggedness and reliability, the TD42 is not particularly fuel efficient and may be subject to cooling issues when not properly maintained. [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). Original engines (until 1996) were fitted with 28 mm gudgeon pins whilst from 08/1996 onwards, Nissan fitted 30 mm pins. The rear seal also changed from a conventional style to a unitized style around September 1997.

TD42T

The TD42T is the turbocharged version of the aforementioned TD42. It was available from 1993. Nissan revised the piston design to accommodate the forced induction by adding extended oil squirters and oil cooling the pistons. Crankshafts were also updated to suit turbo engines. The fuel pumps were upgraded to an 11mm plunger style on these models to handle the increase of fuel supply needed for the turbo application.


TD42Ti

These engines have been fitted with a factory intercooler and were built from the end of 2002 to 2007. In February 2003, this version received electronic control of injection timing; this increased the torque output to 360 N⋅m (37 kg⋅m; 266 lb⋅ft), [1] equivalent to a BMEP of 1.09 MPa. The electronic control version was called the TD42ETi by Nissan. [20] 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. These are the most sought after model of the TD42 family, having the strongest internals and being factory intercooled. Still highly valued due to their simplicity and reliability, the TD42 family has a strong following in the overlanding and offroading markets. Aftermarket support is extensive for the TD42 with many options available both in OEM and performance applications. Nissan ended production in 2007 due to incoming emissions restrictions; in most applications it was replaced by the ZD30 family.

<span class="mw-page-title-main">BMC A-series engine</span> Reciprocating internal combustion engine

The Austin Motor Company A-series is a British small straight-4 automobile engine. Launched in 1951 with the Austin A30, production lasted until 2000 in the Mini. It used a cast-iron block and cylinder head, and a steel crankshaft with three main bearings. The camshaft ran in the cylinder block, driven by a single-row chain for most applications, and with tappets sliding in the block, accessible through pressed steel side covers for most applications, and with overhead valves operated through rockers. The cylinder blocks are not interchangeable between versions intended for conventional end-on mounted gearboxes and the 'in-sump' transaxle used on British Motor Corporation/British Leyland front wheel drive models such as the Mini. The cylinder head for the overhead-valve version of the A-series engine was designed by Harry Weslake – a cylinder head specialist famed for his involvement in SS (Jaguar) engines and several Formula One-title winning engines. Although a "clean sheet" design, the A-series owed much to established Austin engine design practise, resembling in general design and overall appearance a scaled-down version of the 1200cc overhead-valve engine first seen in the Austin A40 Devon which would form the basis of the later B-series engine.

The Nissan H series of automobile engines is an evolution of the Nissan "R" engine which was based on the 1.5-liter, three-main bearing "G" engine used in the 1960s. Both inline-four and inline-six versions were produced. It is a pushrod OHV design with iron block, early models with an iron head, later models with aluminum head. Versions of this motor have been used in many Nissan autos and forklifts, well into the eighties and a version called H20II was in production until 2003. The SD diesels are based on this series of motors

The Nissan L series of automobile engines was produced from 1966 through 1986 in both inline-four and inline-six configurations ranging from 1.3 L to 2.8 L. It is a two-valves per cylinder SOHC non-crossflow engine, with an iron block and an aluminium head. It was most notable as the engine of the Datsun 510, Datsun 240Z sports car, and the Nissan Maxima. These engines are known for their reliability, durability, and parts interchangeability.

<span class="mw-page-title-main">Nissan Z engine</span> Reciprocating internal combustion engine

The Nissan Z engine is a series of automobile and light truck four-cylinder engines that was engineered by Nissan Machinery, manufactured by the Nissan Motor Company from 1979 through August 1989. All Z engines had 4 cylinders, a total of 8 valves and a single overhead camshaft (SOHC). Displacements ranged from 1.6 L to 2.4 L.The Z series' engine blocks were nearly identical to those of the earlier L Series with the exception of the Z24. While the Z16 and Z18 engines had a deck height similar to the earlier L13/L14/L16/L18 variants, the Z24 had a taller deck height to accommodate a longer stroke. The most notable difference between the Z-series engine and its predecessor was the introduction of a new crossflow cylinder head which reduced emissions by moving the intake ports to the right side of the engine opposite the exhaust ports. This change allows the exhaust port velocity to more effectively scavenge the cylinder and reduce reversion pulses to enhance induction. This change also limits maximum valve lift/lobe lift profiles rendering the cylinder head and valve train configuration undesirable for high-performance uses. The Z series evolved into the NA and KA engines which, along with the smaller CA series, replaced the Z series.
