List of Nissan Engines

List Of Nissan Engines

Nissan Motors uses a straightforward method of naming their automobile engines. The first few letters identify the engine family. The next digits are the displacement in deciliters. The following letters identify features added and are order specific based on the type of feature.

Letter Feature Feature type
D DOHC Camshaft
V Variable Valve Lift with Timing Camshaft
S Carburetor Fuel delivery
i Throttle Body Fuel Injection Fuel delivery
E Electronic Port Fuel Injection Fuel delivery
D Direct Cylinder Fuel Injection Fuel delivery
N Natural gas fueled Fuel delivery
P LPG fueled Fuel delivery
R Supercharged Power adder
T Turbocharged Power adder
Ti Turbocharged and intercooled Power adder
TT Twin-Turbocharged Power adder
HR High Response and High Revolution Special

The features/letters follow a specific order and not all features are necessarily listed all of the time. The basic, common features follow this general order:

1 = Camshaft
2 = Fuel delivery
3 = Power adder
4 = 2nd power adder
5 = Special

A good example is the Nissan RB26DETT engine where the feature letters describe an engine with dual overhead camshafts, electronic port fuel injection and two turbo chargers.

The next example is the Nissan SR20DE engine where the feature letters describe an engine with dual overhead camshafts and electronic port fuel injection but leaves off any power adder descriptors because it is a naturally aspirated engine. The popular, (single) turbocharged version of this engine is logically called the SR20DET.

Not all features are necessarily described in the name. For example, the SR20VE engine has dual overhead camshafts but the variable valve lift (and timing) design of the camshafts takes precedence in the naming scheme even though the "V" feature designation doesn't necessarily describe a DOHC arrangement.

A good example of an engine where not all of the feature designation spots are used is the CA18ET engine. The two features listed being electronic port fuel injection designated with the "E" and the presence of a turbocharger designed with the letter "T". The engine has a single overhead camshaft so there is no "D" listed in the name; the camshaft type designation place being left out completely. Nissan does not have a letter designation for the SOHC configuration so the camshaft configuration type is assumed as SOHC if no letter is present.

Lastly, the MR16DDT engine designation describes an engine with dual overhead camshafts, direct cylinder fuel injection and a single turbocharger. This engine also has variable valve timing, but Nissan does not currently have a letter designation for that feature.

Famous quotes containing the words list of, list and/or engines:

    I made a list of things I have
    to remember and a list
    of things I want to forget,
    but I see they are the same list.
    Linda Pastan (b. 1932)

    My list of things I never pictured myself saying when I pictured myself as a parent has grown over the years.
    Polly Berrien Berends (20th century)

    America is like one of those old-fashioned six-cylinder truck engines that can be missing two sparkplugs and have a broken flywheel and have a crankshaft that’s 5000 millimeters off fitting properly, and two bad ball-bearings, and still runs. We’re in that kind of situation. We can have substantial parts of the population committing suicide, and still run and look fairly good.
    Thomas McGuane (b. 1939)
