Serial versions of all-wheel drive SUV Niva (Lada 4 ? 4) traditionally found on CIS roads exclusively with a gasoline engine, although the manufacturer tried to install a diesel engine on this model. For this reason, one of the topics, associated with the popular jeep, it is possible to install a diesel engine on the Niva.
We also recommend reading the article on affordable diesel tuning. In this article you will learn about it, how to increase the power of a diesel engine by installing a special module called tuning box.
Diesel engine, especially in the simple atmospheric version, on serious SUVs is a better option compared to the petrol unit. This motor has many obvious advantages:
- high diesel torque at low speeds is indispensable for off-road vehicles;
- the diesel engine consumes much less fuel, which is important when driving off-road;
- requirements for the quality of diesel fuel are significantly reduced by using atmospheric diesel;
- the greater resource of the diesel engine before serious repair allows to operate actively and long such engine;
The main disadvantage is ??vulnerability of high-precision diesel fuel equipment, as well as the complexity and high cost of further repairs. Diesel injectors and diesel injectors often fail in the power supply system of a diesel engine. The presence of turbocharging can also cause certain difficulties during operation (turbodiesel), as the condition of the turbine strongly depends on the quality of fuel and diesel engine oil.
Serial Niva with diesel engine
The idea of installing a diesel engine on the Niva model 2121 from the very beginning, engineers at the plant tried to implement it. For Niva it was supposed to use the domestic version of the 1.5-liter turbodiesel engine. With such a unit, the prototypes could not effectively cope with off-road driving due to insufficient power. The next step was the installation of a similar diesel on the 3rd and 5th door version of the Niva, but already with increased workload to 1.9 liters. These attempts were unsuccessful, diesel Niva with these engines did not fall into the series.
Rejecting the idea of putting your own diesel on Niva, engineers have proposed the option of installing a Peugeot diesel engine. The French diesel received the factory index Peugeot xud9sd, has several versions with different forcing (69-75 c.c.) and is widely represented on various car models.
Engine design: diesel, in-line, 4-cylindrical, with a longitudinal arrangement. Working volume: 1905 cm3. One of the modifications of this diesel engine when installed on the Niva provided the car with such dynamic performance and performance characteristics:
| Maximum power: | 48 kw (69 c.c.) at 4600 about / min |
| Обертаючий момент: | 121 Nm / 2200 about / min |
| Maximum speed: | 120 km / year |
| Розгін 0-100 km / h: | 25 sec |
| Average fuel consumption per 100 km: | 8,0-8,7 l |
The field with such a diesel turned out to be economical and showed itself well off-road, since the Peugeot xud9sd diesel engine provided the all-wheel drive car with decent torque at the "bottom". An additional advantage of the imported diesel engine in Niva was its reliability and relative ease of repair and maintenance..
We also recommend reading the article about it, how to accurately measure the compression of a diesel engine. In this article you will learn about possible faults and ways to measure diesel compression to get accurate results.
As for the dynamics, Levels 2121 with the Peugeot xud9sd engine accelerated to "hundreds" very slowly. Emphasis was placed on the main purpose of the car - increased off-road on total off-road. The Niva model with a Peugeot diesel engine has entered the series, but the car was produced in limited batches, and also went exclusively for export. IN 2009 year serial factory production of diesel Niva completely stopped.
Niva-Chevrolet diesel
Further attempts to almost "officially" install a diesel engine in Niva (Niva-Chevrolet model) made in the city of Togliatti. To do this, the tuning studio called "Theme-Plus" received permission from the manufacturer GM-AvtoVAZ. The main refinement of the Niva-Chevrolet model was the installation of an Italian diesel engine manufactured by Fiat paired with a Japanese transmission Aisin.
| Working volume: | 1929 cm3 |
| power: | 90 c. |
| Максимальний крутний момент: | 195 Nm |
| Average fuel consumption per 100 km: | 7,5 l |
Installation of the diesel engine and the improved transmission allowed to provide tuning model Niva-Chevrolet 1.9 TD high torque in the low rev range, as well as acceptable acceleration dynamics. Such a car can not be considered serial, but this version of the Niva-Chevrolet diesel is noticeably closer in level to the factory assembly. The only downside is the greatly increased final price of upgraded tuner SUV.
We install a diesel engine in Niva
One of the available options is self-installation of a diesel engine on the Niva. To do this, you can use the services of large tuning studios or private professionals, engaged in the completion of cars. You can also install a diesel on the Niva yourself with some experience and a specialized tool. You need to be prepared for that, that for lawful operation of the car after engine replacement it is necessary to register the made changes in the corresponding state bodies.
In the process of selecting a diesel unit, many are wondering, which diesel to put on the Niva. There is a sufficient number of diesel engines, which can be installed on this car. Diesel engines of Japanese and European brands are most often installed in Niva with their own hands. The main requirement is the appropriate physical dimensions of the power unit for placement in the hood space Niva.
The need to make changes to the design begins with the features of the diesel engine. The second aspect is the increase in the load on the front axle after the installation of a diesel engine on the Niva, as the motor of this type often appears more heavy. For this reason, it is necessary to further strengthen the suspension, and the body after placing the engine. The standard gearbox will almost always be replaced.
In the list of the general changes in a design of the Field under the diesel engine are noted: replacement of front engine mounts, modified pallet, changes in the exhaust system. The engine cooling system is also subject to modernization. The cooling radiator is often changed (the radiator from the GAZ Gazelle car approaches).
Changes are also made to the chassis, individual elements are replaced by reinforced ones. For ordinary Niva, they can be borrowed from Niva-Chevrolet. As for the operation of the diesel engine, the installation of a diesel fuel heating system is recommended separately.
The easiest option to replace the engine for the car Niva will be a diesel engine Peugeot xud9sd. The main advantage of this diesel is its mounting, similar to the regular gasoline unit. This feature greatly simplifies the installation of a diesel engine on the Niva. Also, the Peugeot XUD9SD does not require a gearbox change, allowing to use native check point VAZ.
You can also install a Peugeot diesel with the xud index on the Niva 11, but in this case the check point will already need to be changed. The VAZ box with this engine will not last long. The solution is a gearbox from the Fiat Polonez model. Additionally, you will need to install another clutch. Diesel engines from Japanese cars are installed in Niva no less often. Suitable units with the Toyota 3c index / ct power 80 and 100 c.. To replace the gearbox, you can use a 5-speed gearbox from the Noah model made by Toyota.
The best option would be a diesel engine and gearbox, which were originally designed to work in pairs. In this case, the task is simplified by matching all mounting points, as well as the coincidence of the axes of the shafts of the internal combustion engine and transmission. This approach eliminates difficulties in combining the diesel engine and transmission, and significantly increases the service life of connected nodes. No need to calculate, what is the torque that can be withstood by a box with different diesel engines.
