Engine Nissan YD25

The 2.5-liter diesel engine Nissan YD25DDTi or YD25 has been produced since 1998 and is installed on the most popular minibuses, pickups and SUVs of the company. This motor replaced the CD20 and TD25 on some cars. The cylinder block here is an in-line 4-cylinder, cast iron, with a cylinder diameter of 89 mm. Inside the block there is a crankshaft with a piston stroke of 100 mm, and the length of the connecting rods is 154.5 mm. All this gives 2.5 liters of working volume.

Engine Nissan HR16DE/H4M

The Renault-Nissan HR16DE / H4M engine is a logical continuation of the Renault K4M internal combustion engine. The motor was modernized, mainly the gas distribution mechanism and electronic control were changed. Also, the engine was equipped with a timing chain drive, new camshafts and two fuel injectors per cylinder. Hydraulic lifters were removed from the engine (adjustment by selecting pushers every 100 thousand km). The variable valve timing system is retained on the intake shaft. The engine has become more economical than its predecessor, more powerful and more environmentally friendly. Continue reading Engine Nissan HR16DE/H4M

Engine Nissan KA24DE/E

In 1988, the Z24 series was replaced by the KA24 gasoline power units. It is already problematic to buy the very first modifications of the ka24e internal combustion engine in our time, since their production was discontinued in 1991 due to modernization. However, especially for several model lines intended for the European and North American markets, production is periodically resumed. Since its inception, the engine has been modified and modernized several times, which was reflected only in the power and CO level. For the rest, nothing of the in-line power unit used in the device has changed. Continue reading Engine Nissan KA24DE/E

Engine Nissan QG15DE

The QG15DE engine is developed on the basis of the QG16DE, it was created with an eye to replacing the GA15DE. The manufacturer has reduced the diameter of the cylinders of the cylinder block. In addition, other pistons were used in the engine. The engine has an increased Compression ratio. But in general, for the most part, the engine is a repetition of the QG16DE, which served as a base for it. In order to reduce the toxicity of the outlet, the EGR system was used on the engine, a mechanical throttle valve was installed. This approach made it possible to slightly mitigate the environmental damage caused by vehicle outlet. Continue reading Engine Nissan QG15DE

Engine Nissan QG16DE

The 79 kW QG16DE engine with two camshafts has four valves per cylinder. The engine camshafts are driven by a chain. The cylinder block of the QG16DE engine is a single casting that forms the cylinders, a cooling jacket, the upper part of the crankcase and five crankshaft bearings made in the form of crankcase baffles. The block is made of special ductile iron with cylinders bored directly into the block body. The engine main bearing caps are machined with blocks and are therefore not interchangeable.
