K4M engine faults and repairs
Renault Logan K4M 1.6 liter engine. 102 hp is not new, a number of its various modifications are used by Renault since 1999 on models Renault Megane, Renault Clio II, Renault Laguna and others. It is a development of K7M series, with a new cylinder head, already 16 valve. There are many differences: another head with two camshafts, the camshafts themselves are light, other pistons, hydrocompensators, etc. Motors are available with and without phase regulator, compression ratio varies from 9.5 to 10, with this and with the firmware are associated with a slight variation in the power output of the engine, otherwise all K4M are identical. The whole list of indices after the name K4M shows: toxicity standards (Euro-3\4\5), gearbox type, the presence of a phasoregulator, compression ratio and other trifles related to the peculiarities of installation in each particular car. In nature there is a modification of this motor called K4M RS, on wide shafts, sawed channels it gives out 135 hp with a volume of 1.6 liters.
To minuses of 16-valve motor we will refer expensive spare parts, timing belt K4M at break bends valves, so once in 60 thousand kilometers it is necessary to change rollers, the belt itself and drive with a calm soul. In addition, there are failures in operation, from low-quality fuel float revolutions. Compared to the 8-valve engine, 16V works quieter, more economical, there are no vibrations and many other pluses. If you choose with what engine to take Logan/Sandero/Duster, then unequivocally 16-valve K4M is your choice. In the case of bigger cars – Duster, Megane, etc. look at the 2.0 liter motor.
It is worth saying about the frequently occurring malfunctions, the engine k4m not seldom troit, the problem is usually in the ignition coil, injectors, plugs, measure the compression and proceed from this.
Unstable operation, floating revs on k4m logan 1.6 engine is usually caused by the crankshaft position sensor or ignition coil.
Renault K4M 16 valve engine tuning
Chip tuning
Ordinary engine chip, at the same time with the replacement of the exhaust is able to slightly improve the danimicheskim indicators of the motor, +\- 120 hp to get quite possible. It can be supplemented by installing shafts drivtech 10 phase 270, a little wider than the standard, will go a little more cheerful and give a little more hp. To go further you need to think of something else.
Compressor
Just like on K7M or K7J, if you want to, you can add a RK-23 compressor to the engine and inflate about 140-150 hp. The compression ratio of standard K4M is not too high, 0,5 bar will hold. There are no ready-made kits for this motor, but if you address to the manufacturer, you will get the necessary configuration for a particular car. To implement the project you will need Volgov injectors, straight-through exhaust, shafts phase 270-280, and to configure all this online will need an engine control unit Abit.
