Pavlovsky Bus Plant is one of the largest bus manufacturers in Russia. All serial PAZ buses were produced on the basis of units and assemblies of medium-capacity GAZ trucks.
New model
In 2012, the plant put into serial production a new bus model - PAZ-320412. The main purpose of the car is the inner-city transportation of passengers and use as a corporate or business vehicle. Depending on the wishes of the client, the bus runs with 21, 24 or 29 seats for passengers. The total capacity of buses is from 52 to 60 people. The bus length in this case is from 8.56 to 8.8 m.

Design features
The bus is equipped with an all-metal wagon-mounted body with two doors for passengers to enter and exit. As a power unit, four-cylinder turbocharged diesel engines YaMZ-534 and Cummins ISF 3.8 are used, mounted longitudinally in the front of the body. Motors develop a capacity of 166-170 liters. from. and comply with the Euro emission standards (3 or 4).
The gas version of the Cummins engine has six cylinders and develops power up to 197 forces. Thanks to these motors, the general technical characteristics of the PAZ-320412 were significantly improved. For example, buses can be equipped with a five-speed manual gearbox or a six-speed Allison automatic. The gas version of the bus is equipped only with a manual gearbox. In the photo below, a gas engine installed on the PAZ-320412.
Regardless of the type of box, buses can accelerate to 100 km / h with a total weight of 11,500 kg. Modern materials and technologies have significantly increased the resource of the bus. The manufacturer gives a guarantee for the car for 2 years or 100 thousand km. run. In the photo, the PAZ-320412 bus in urban conditions.
Diesel fuel or gas can be used as fuel for engines. The diesel tank has a capacity of 95 liters, while the gas version has six 62-liter gas cylinders and a reserve 50-liter liquid fuel tank. Diesel engines provide good profitability of the PAZ-320412 bus. The fuel consumption of a fully loaded car in the urban cycle does not exceed 24 liters.
The bus pendants retained semi-elliptical springs in their design. Additionally, shock absorbers were included. Two pneumatic cylinders and a body position adjuster are installed in the rear suspension.
Machine equipment
The PAZ-320412 standard equipment includes a pneumatic brake drive, hydraulic power steering, a motor brake (which helps to reduce the braking distance) and an anti-lock brake system. In a standard heating system, an autonomous heater is installed by default. Four heaters with individual fans were used to supply warm air to the passenger compartment. The liquid heating in them is combined - from the main engine and an autonomous heater. In the photo below, another instance of the PAZ-320412.
All buses can be equipped with a GLONASS navigation system, which is used to track the route of the vehicle. On request, all passenger seats in the bus can be equipped with seat belts and adjustable backrests. In addition, at the request of the buyer, the PAZ-320412 can be equipped with heated mirrors, fog lights and a tachograph.
Driver's seat
The driver sits in front of the body in a semi-closed cab. The bus body can be made both with an individual driver's door, and without it. The driver’s workplace is equipped with a seat equipped with a seat belt. The seat itself is adjustable in distance to the steering column and in the height of the cushion. The angle of the backrest can also change, as well as the height of the headrest. Thanks to such adjustments behind the wheel, a driver of any height and weight can comfortably accommodate.
The PAZ-320412 bus is equipped with a completely new combination of devices that allows you to control the operation of almost all components of the machine. In combination are:
- Tachometer.
- Speedometer.
- Two pressure indicators in the circuits of the pneumatic brake drive.
- Fuel gauge
- Coolant temperature sensor.
- LCD information board.
- Warning lights.
