Daihatsu H-series engine


The Daihatsu H-series engine is a range of four-stroke four-cylinder, internal combustion piston engines, designed by Daihatsu, which is a subsidiary of Toyota. These engines were produced from 1987 through 2009. Ranging from 1.3 L up to 1.6 L, these four-cylinder engines were built with lightness in mind, featuring a hollow crankshaft and camshaft, and the weight of a four-cylinder engine is similar to the 1.0 L three-cylinder CB engines. The H-series engine has aluminium engine blocks and cylinder heads, timing belt driven heads, naturally aspirated, water-cooled engine cooling system, equipped with both carburetors and Multi-Point Fuel Injection and only available in 16-valve SOHC design.

HC (1.3 L)

First appeared in Daihatsu Charade G102/112 in 1987 and discontinued in 2009. The displacement is 1.3 L, bore and stroke is 76.0 mm x 71.4 mm. Available with carburettor and fuel injection. The compression ratio is between 9.0:1 to 9.5:1. Maximum power is between @6000–6500 rpm with @3200–4500 rpm of torque. This engine later replaced by K3-DE/VE engine.
Applications:
First appeared in Daihatsu Applause in June 1989 and discontinued in 2008. The displacement was increased to 1.6 L by increasing the stroke size of HC engine to 87.6 mm but retaining the same 76.0 mm bore size. Available with carburettor or fuel injection. The compression ratio is between 9.5:1 to 10.5:1. Maximum power is between @5600–6300 rpm with @3200–4800 rpm of torque.
Applications:
First appeared in Daihatsu Charade in 1993 and discontinued in 2007. The displacement was decreased to 1.5 L by decreasing the stroke size of HD engine to 82.6 mm but retained the same 76.0 mm bore size. Only available with fuel injection. The compression ratio is 9.5:1. Maximum power is between @6000–6300 rpm with @3600 rpm of torque. This engine later replaced by 3SZ-VE engine.
