Bus LiAZ-5293: specifications, photo

The city bus LiAZ-5293 is a low-floortype of public transport with increased capacity. The machine is used in large cities, where there is an intense flow of passengers. LiAZ-5293 is produced since 2006 at the Likino plant. Technical indicators of the bus meet the relevant standards. Different models are equipped with several variations of domestic and imported power units.

Used engines

The first 4 years of production the bus in questionequipped with a diesel engine Caterpillar on 6 cylinders. Its capacity is 350 horses, the volume is 7 liters. Fuel consumption in the mixed cycle is about 30 liters per hundred kilometers. Used automatic transmission, the speed to a maximum of 90 km / h. The power unit complies with the Euro 3 standard.

The next modification of the engine under the nameCummins 6ISBE had better design, turbocharging and improved environmental performance. The maximum speed remained at the same level, but the fuel consumption was reduced to 23 l / 100 km. Soon there was a variation of the motor on gas, with a force of 252 horses and a volume of 8.2 liters.

The last variation, which is set toLiAZ-5293, is a YaMZ engine with 240 horsepower. The rotational speed was 2,300 revolutions per minute, the working volume - 6,5 liters. The power unit corresponds to Euro 4, equipped with an automatic box, consumes about 27 liters of diesel fuel per 100 km.

Salon equipment

The salon is ventilated in two ways: naturally through side windows and forced by fans on the ceiling. The heating system operates on the heat generated by the power unit. There is also a stand-alone liquid-type heater. Thanks to this design, the LiAZ-5293 bus warms evenly. The cooling system in turn provides comfortable conditions for passengers in the summer.

The driver's place is fenced off from the salonnoise-isolating partition, which allows the chauffeur to concentrate better on management. To announce stops and other information in the cab is provided with a loudspeaker. This bus has a high safety factor, which allows not to spend a lot of resources for maintenance and repair. The estimated life of the body is 12 years, and internal systems can easily withstand hundreds of thousands of kilometers.

disadvantages

Despite certain advantages, incar LiAZ-5293 there are some flaws, passed from his predecessors. The realities of the operation show that the ASCP system is placed inefficiently and consumes some of the useful space. The standard dimensions of the body remained from the previous model, which did not contribute to a significant improvement in passenger comfort.

In addition, the driver's door lock (LiAZ-5293)often freezes after parking on the street. Not entirely satisfied with the work of the suspension, the system of which often does not respond adequately to the inclination of the bus towards the sidewalk to reduce the landing height. It leaves much to be desired for the quality of the assembly, as well as not fully thought out system of opening the doors.

Features

It should be noted that LiAZ-5293, whose photopresented below, has become a kind of intermediate link in the development of truly efficient city buses. The first version of this modification was released in 2006 by the Likino Bus Plant. Starting a large batch of cars (100 pieces) ordered Nizhny Novgorod passenger avtotrans.

The buses in question are being operatedeverywhere in major cities of Russia. In Moscow, they work in the 11 bus fleet, equipped with an environmentally friendly engine with a gas installation. Underestimated vehicle floor (height on the road - 3.4 cm) and wide doorways provide a quick landing of passengers' landing, which reduces the stay of the car on the route.

Conclusion

It can be concluded that LiAZ-5293 isa certain breakthrough in the structure and design of low-floor city buses. I am pleased with the renovation of the interior, the well-designed ventilation and heating system. The exterior is also quite decent, there are several color schemes. Fuel meets environmental standards.

However, a number ofquestions on the underfundings of the running gear, in particular the suspension, the door opening system and the thoughtful layout of the internal equipment. I want to believe that the developers will not stop at this, but will take constructive steps to improve the driving performance and comfort of passengers. At least, to this there are all the prerequisites, which show that the design achievements are aimed at the integrated improvement of city buses.
