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.

Engine Nissan QR20DE

The QR20DE powertrain does not represent anything outstanding. This is a conventional 2.0-liter engine with an aluminum BC and a short service life. According to the manufacturer, if you use the QR20DE unit sparingly, then its resource will reach 200 thousand kilometers. Unlike its predecessor, the SR20DE, the new QR20DE features individual ignition coils and an improved cylinder head. The IFGR system on the intake shaft was also added, and balance shafts began to be responsible for the smooth operation. Due to the lack of hydraulic lifters, it will be necessary to adjust the valve clearances every 100 thousand kilometers. Continue reading Engine Nissan QR20DE

Engine Nissan SR18DE

The Nissan SR18DE engine appeared in 1992 and was an evolution of the SR18Di, with multipoint multipoint fuel injection instead of single injection. It is worth noting that the engines for the Nissan Pulsar and Sunny GTI have a high power (140 hp 6400 rpm) and a Compression ratio of 10 units. Structurally, the SR18DE is almost identical to the older “brother” SR20DE. The gas distribution mechanism for SR18DE engines is driven through a chain, there are hydraulic lifters (the engine does not need to adjust the valves), the ignition system is single-circuit.

Engine Nissan SR20DE/DET/VE/VET

The SR20DE powertrain first appeared in 1989 and received an aluminum cylinder block with dry cast iron liners. The SR20 series engines received several modifications, the most powerful of which was intended for the Nissan X-Trail GT SUV. This variant was a turbocharged version with 212-248 intake camshafts, 8.0-11.0 mm lift and 244 outlet cams and 11.3 mm lift. The reliability and durability of the 2.0 liter Nissan SR20 series engines suggests that there are no global shortcomings. Among the minor drawbacks, the floating XX (idle) and periodic breakdowns of the mass air flow sensor (mass air flow sensor) were noted. Continue reading Engine Nissan SR20DE/DET/VE/VET

Engine Nissan QG18DE

The 1.8 liter QG18DE petrol engine was used in Nissan vehicles with high torque at low revs. Such an engine is considered very economical – fuel consumption is fixed at about 7 liters per 100 km. mileage, and 97% of the torque is produced by it in a low range of 2400-4800 rpm. Environmental cleanliness and low toxicity is ensured by a special design of the piston crown with a neutralizer surface of up to 50%. Continue reading Engine Nissan QG18DE
