Troubleshooting and repair of QG16DE engine
The Nissan QG16DE engine was developed by Aichi Machine Industry as a replacement for the GA16DE. Based on the QG16, a motor with increased displacement up to 1.8 liters was created. QG18DE, as well as the junior QG15DE. Our test subject is a simple motor with a cast-iron block and not bad power, almost 120 hp from the working volume of 1.6 liters, but in CIS countries the motors are strangled to 106-109 hp. The timing system uses a chain (about it a bit below), there is a standard set of technologies: the system of changing the phase of gas distribution on the intake shaft (CVTC), the system EGR (For re-combustion of exhaust gases, thereby reducing the toxicity of exhaust), electronic throttle, intake receiver with swirlers and other less significant technologies.
There are no hydrocompensators, hence the need to periodically adjust the valve clearances by adjusting washers. When it is necessary to do this, will prompt a characteristic metallic knock of the engine Almera Classic.
There are no serious and obvious diseases of the engine, but some things are worth looking at:
- Stretching of the timing chain on QG16DE. This is a common case for these engines, symptoms: the motor starts badly, there are failures of traction, floating idle, increased noise. The problem is treated by simple replacement of the chain, the chain resource is about 150 thousand kilometers, the price is moderate.
- Does not start QG16DE. Not a rare problem when the car starts with the n-th time. The issue is solved by cleaning the throttle valve and/or replacing the gas pump screen, in extreme case by buying a new gas pump.
- soft whistling. Source – alternator belt, solved by replacing the roller and belt.
- Twitching at low speeds, this is a feature of the engine, the problem is solved by a new firmware.
In addition, these engines have short-lived catalytic converters, replacement is worth a lot, likes to pollute the throttle and reduces the reaction to the accelerator pedal, this issue is solved by its usual cleaning, and in general, the motor is ordinary, as for a budget car. If you choose for Nissan Examples, QG16DE is weak and the car will not go, it is better to look in the direction of 2-liter QR20DE, the truth for Almera Classic QG16 is normal, however, there are no other options.
In 2006, the successor of this motor came out and it was called HR16DE.
Engine number QG16DE 1.6
The number is located on the cylinder block on the right side. This place is very vulnerable and often rusts, to keep the number intact, coat it with a heat-resistant varnish.
Nissan QG16DE Engine Tuning
Chip tuning
To the question “How to increase the engine power of Nissan Almera Classic / Examples”, often sound the answer “Make chip tuning, here I went … “. This is all nonsense, a simple chip situation can not change, if something and will be added, it will be difficult to feel it. So how do you tweak an engine? Atmospheric motor, any, is finalized by proven moves, shafts with moderate phase and lift are put, receiver, porting of the cylinder-head is done, straight-through exhaust with spider 4-2-1, it is tuned and drives. On the engine QG16DE sports camshafts and receiver in the sale is not found, we will be satisfied with what we have. We put a straight-through exhaust with a 4-2-1 spider, we give the cylinder head for boring and grinding of channels, we put big valves, we flash and get up to 130 hp without loss in resource. Want more, then you need to make camshafts to order with a wide phase and high lift, put 4 throttle intake, but to build an evil atmo on the motor QG16DE is not rational, for this there are TAZs)).
Turbine/Compressor on QG16DE
In general, the idea is good and realizable, but here is a weak link gearbox, so the idea of turbine discard immediately. There remains a compressor, it can be put even without changing the gearbox, with a compression ratio of 9.5, we blow to 0.5 bar without trembling in the knees, the box will not allow you more anyway. To successfully install the compressor on the QG16DE, we will need … compressor of course, we will take the popular PK-23-1 or analog, straight exhaust with spider 4-2-1 and online tuning, we will get about 150-160 forces without problems. Want more? Do a swap of a more powerful and initially adapted to tuning motor, no variants.
