Nephaz bus 4208 technical specifications. Minimum version equipment

To transport work crews to the site of construction work, when the capabilities of a regular bus are not enough, NEFAZ 4208 comes to the rescue with an improved version of itself.

Shift buses last year releases are distinguished by increased technical characteristics. They are specially designed for movement in all weather and climatic conditions.

The constant modernization of the NEFAZ 4208 all-wheel drive bus since 1989 has resulted in a perfect vehicle.

The most famous models of this series are produced with the NEFAZ 4208 11-13 configuration, with 24 passenger seats (22 + 2 in the driver’s cabin) and a power of 240 hp.

Separately, it is worth noting the NEFAZ 4208 24 generation with a power of 280 hp. and different quantities seats. The configuration with markings 10 or 11 has a passenger capacity of 20 or 22 seats, respectively. Designations 8 or 9 include 16 passenger seats.

The mini-variant NEFAZ 4208 03, which is rightly called municipal equipment, includes only 8 passenger seats. It is particularly compact, but, nevertheless, its declared power reaches 260 Horse power.

A special one was created for transporting a small number of workers (shift workers, fishermen or hunters). There is only a natural ventilation system here, but this makes the functionality of the presented model no worse than the NEFAZ 4208 11 13 crew bus with a turbofan.

Main technical characteristics

The dimensions of each model in this series may differ slightly, but the average dimensions are as follows - 8.5 * 2.5 * 3.3 m. Maximum speed The speed the bus can reach is up to 85 km/h. Fuel tanks are located on the right and left sides of the chassis.

A manual 5-speed gearbox is what you need to select speed in conditions of constant variability of road conditions. Manual transmission and dry double-disc clutch are a guarantee of strength and reliability. The risk that the bus will get stuck on the way to the work site is minimized, since the road rise can be as steep as 31%.

If the first models had a built-in engine that met Euro 1 standards, now its functionality is focused on environmental class Euro 4 and even Euro 5.

Externally, the body has the appearance of a closed van. The main door is located with right side and has a low entrance, and also has an emergency exit (hatch) in case of unforeseen circumstances. Single doors open outwards for complete convenience. A spare wheel is installed on the rear wall of the outer side.

Inside the cabin

Soft safety seats with a fixed backrest and tilt angle adjustment, as well as two or three-point seating, are an excellent solution for transporting workers.

The folding table, which is located opposite the main entrance to the salon, is convenient to use for a snack. Moreover, there is an intercom in the cabin for communication with the driver’s cabin, as well as a radio receiver. Excellent thermal insulation keeps the cabin warm throughout the entire transport of workers.

Double glass windows with tempered glazing have received excellent recommendations for protection against damage, thereby providing additional proof of safety.

Let's take a closer look at the heating and ventilation system, at least using the example of NEFAZ with modification 4208 24 - a full-fledged rotation bus.

Possible additions

Glass tinting with special films or finishing with curtains is allowed. If constant travel in difficult climatic conditions is expected, then you can install air conditioning or additional heating. It is possible to equip it with a winch.

NefAZ-4208 is a rotation bus for transporting construction personnel or repair workers. The model is assembled on a platform. After on the platform in end result More than 20 modifications were collected.

Production began in 1989, and later the machine was modernized several times in all aspects. Visually, it is impossible to find a difference in the design of the cabin compared to the co-platform one; they are the same.

Design

The cabin is represented by a massive bumper with rectangular headlights and a large radiator grille divided into sections. On the side there are huge swollen wheel arches, in front of which there are steps.

Behind the cabin is an all-metal van body with one entrance door. The passenger cabin of the NefAZ-4208 is quite comfortable, because it is treated with thermal insulation and double glazing to reduce noise levels.

The dimensions of the car differ depending on the modification:

• length – 8500-9710 mm;
• width – 2550 mm;
• height – 3370-3430 mm;
• wheelbase – 3340-4100 mm;
• ground clearance - 390 mm.

The model is actively used in fire services; a crane is installed on the roof, and retractable trays for rescue equipment are installed under the body. The cabin now seats 11 people, and breathing apparatus appears inside.

Salon

For passenger transportation The van body contains two rows of double seats. Depending on the modification, from 14 to 28 seats are installed. The NefAZ-4208 seats do not have any adjustments, but are equipped with seat belts.

Passengers do not have direct contact with the driver; for this purpose there is an intercom. The bus is equipped with a double heating system, the first operates from a liquid heater, the second is connected to the internal combustion engine cooling system.

Engine and gearbox

The platform on which the car is built implies the installation of various units of different power.

1. Models M and 34 (written after the name) are equipped with a KamAZ-740.622-280 engine - a diesel V8 with a volume of 11.7 liters. The engine is turbocharged with liquid cooling, producing 280 horsepower and 1177 H*m of torque.
2. The NefAZ-4208-11-13 modification is also equipped with a 10.8-liter V8. The turbocharger receives cooled air, which made it possible to squeeze out 240 hp. and 1177 units of torque transmitted to all wheels.
3. Model 41 is represented by a modernized V8 unit from the 34th modification. The modernization made it possible to obtain an output of 260 horsepower and 1079 units of torque. This installation has been converted to gas fuel.

The pair is either a 10-speed manual transmission. For an additional fee, you can install a 9-speed gearbox from ZF. The transmission of torque from the box occurs through the transfer case using a double-sided gearbox. There is a locking of the center and cross-axle differential.

Performance and suspension

The NefAZ-4208's maximum speed of 90 km/h is enough not to break the rules traffic. The only upsetting thing is the consumption, equal to 40 liters per 100 kilometers. The car performs well off-road; you can climb 30% hills without any problems. In normal condition, you can drive into a ford with a depth of no more than 80 cm. In 15 minutes, the car is upgraded, which increases the depth of the ford to 150 cm.

The spar frame of the bus is made of durable steel, on which the suspension is installed. The chassis is represented by a dependent design on leaf springs with sliding back. The front springs receive rubber buffers, the rear reaction bars. This suspension allows you to withstand a little more than two tons of weight.

The NefAZ-4208 bus stops using 400-millimeter drum mechanisms. There is a motor retarder system pneumatic type for auxiliary braking in emergency situations.

Price

The minimum cost of a car is 3,500,000 rubles. Longer modifications will cost more, and for a gas internal combustion engine you need to pay 500,000 rubles more. The price tag is not the highest for this category of transport, but in fact the amount is impressive.

Minimum version equipment:

• hydraulic booster;
• auxiliary heater for interior and van;
• engine pre-heater;
• central tire inflation system.
