The C family was Mazda's first large piston engine design. It is not certain whether Mazda has a name for this collection of engines, and it is uncertain precisely which ones are related.

PC

The 985 cc (1.0 L; 60.1 cu in) PC engine featured a 70 mm (2.8 in) bore and 64 mm (2.5 in) stroke. It was an eight-valve SOHC design and was designed for rear wheel drive longitudinal applications. The PC produced 45 hp (34 kW) and 51 lb⋅ft (69 N⋅m) in the export market 323.

Applications:

TC

The 1,272 cc (1.3 L; 77.6 cu in) TC had a 73 mm (3 in) bore and 76 mm (3 in) stroke; a bored and stroked version of the PC. Used in the 1970, 1973, and 1977 Mazda Familia, and the 1979 - 1984 Mazda Bongo / Ford Econovans as the smaller engine option, the larger being the 1.6 L Mazda NA engine. For 1977 a new, prize-winning lean burn version of the TC was developed for the new FA-series Familia, using a carburator with an EGR valve.[1] Thus equipped, the TC weighs 127 kg (280 lb).[1]

Applications:

UC

1,415 cc (1.4 L; 86.3 cu in) (77.0x76.0 mm) - A larger-bored version of the TC, used in the 1978-1980 Mazda GLC. Produced 70 hp (52 kW). This was also used in the 79-84 E1400/Econovan and for the new 1984 Ford Econovan as the base model engine. Other options were the 1.8 L F8 or 2.0 L FE petrol engines or the 2.0 or 2.2 L R2 diesel engine. In continental Europe the Econoline/Mazda E-series continued to use the UC engine until at least 1990, in a version which produces 48 kW (65 PS).[3] In some parts documentations, it is referred to as the D4, however no UC engine block was ever stamped D4. in 1980, this engine (and the smaller TC) was modernized and turned into the new E-series engine, intended for front-wheel drive applications.

UB

The original 1966 Luce 1500 used a 1,490 cc (1.5 L; 90.9 cu in) SOHC inline-four with square 78 mm (3.1 in) bore and stroke. This engine, also used in the Capella and Grand Familia for a short while, was replaced by the stroked NA engine (below).

Applications:

NA

The 1,586 cc (1.6 L; 96.8 cu in) SOHC NA engine was a UB, stroked (to 83.0 mm or 3.3 in). JDM output was 100 hp (75 kW) at 6000 rpm, with maximum torque of 14.0 kg⋅m (137 N⋅m) at 3500 rpm. US-spec was 70 hp (52 kW) at 5000 rpm, with maximum torque of 82 lb⋅ft (111 N⋅m) at 3500 rpm with a single Nikkei carburetor. The rest of the world received a 75 hp (56 kW) version. Later on, this engine was also referred to as H6.

Applications:

VB

A stroked (to 94.0 mm) 1.8 L (1796 cc) version of the UB/NA, retaining the 78.0 mm bore (3.07 in × 3.70 in), was used in the 1968-1972 Luce 1800 and the 1975-1979 Mazda B1800s for the US market. In Canadian market B-series trucks, it was installed as early as 1970. Output for the 1972 Luce was 100 PS (74 kW) JIS at 5500 rpm and 15.5 kg⋅m (152 N⋅m; 112 lb⋅ft) at 3000 rpm. Export model outputs varied, with European market models claiming 104 hp DIN (all other figures remaining the same).[5]
