City bus LiAZ-5293 is a low-floor type 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 Likinsky plant. The technical indicators of the bus meet the relevant standards. Different models are equipped with several variations of domestic and imported power units.
The first 4 years of production, the bus in question was equipped with a Caterpillar diesel engine on 6 cylinders. Its capacity is 350 horses, the volume is 7 liters. Combined fuel consumption is about 30 liters per hundred kilometers. Automatic transmission is used, the maximum speed is 90 km / h. The power unit complies with Euro 3.
The next engine modification called Cummins 6ISBE had a more advanced design, turbocharging and improved environmental performance. Maximum speed remained at the same level, but fuel consumption decreased to 23 l / 100 km. Soon there was a variation of the gas engine, with a power of 252 horses and a volume of 8.2 liters.
The last variation, which is installed on the LiAZ-5293, is a YaMZ engine with 240 horsepower. The rotation frequency was 2,300 rpm, the working volume was 6.5 liters. The power unit corresponds to Euro 4, is equipped with an automatic transmission, consumes about 27 liters of diesel fuel per 100 km.
The interior is ventilated in two ways: naturally through the side windows and forcibly with the help of fans on the ceiling. The heating system operates on the heat received from the operation of the power unit. There is also an autonomous liquid type heater. Thanks to this design, the LiAZ-5293 bus is evenly heated completely. The cooling system, in turn, provides comfortable conditions for passengers in the summer.
The driver's seat is fenced off from the passenger compartment by a soundproofing partition, which allows the driver to better concentrate on driving. To announce stops and other information, a loudspeaker is provided in the cab. The bus in question has a high margin of safety, which allows you not to spend a lot of resources on maintenance and repair. The estimated resource of the body is 12 years, and internal systems can easily withstand hundreds of thousands of kilometers.

Despite certain advantages, in the LiAZ-5293 car there are some flaws that have passed from its predecessors. Operational realities show that the ASKP system is placed inefficiently and eats up part of the usable space. The standard body dimensions 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. The suspension does not quite satisfy, the peeling system of which often does not respond adequately to the inclination of the bus towards the sidewalk to reduce the landing height. The build quality and the not well thought out door opening system leaves much to be desired.
It is worth noting that the LiAZ-5293, the photo of which is presented 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 Likinsky Bus Plant. The starting large batch of cars (100 pieces) was ordered by the Nizhny Novgorod passenger car.
The buses in question are operated everywhere in the large cities of Russia. In Moscow, they operate in 11 bus fleets and are equipped with an environmentally friendly gas engine. The underestimated floor of the vehicle (height on the road is 3.4 cm) and wide doorways provide a quick landing for disembarkation of passengers, which reduces the stay of the car on the route.
It can be concluded that LiAZ-5293 is a definite breakthrough in the construction and design of low-floor city buses. I am pleased with the update of the interior, the well-developed ventilation and heating system. The exterior is also quite decent, there are several color schemes. Fuel meets environmental standards.
However, there are a number of questions regarding the undercarriage defects, in particular the suspension, the door opening system and the well-thought-out layout of the internal equipment. I would like to believe that the developers will not stop there, but will take constructive steps to improve rideability and passenger comfort. At least there are all the prerequisites for this, which show that the design developments are aimed at the comprehensive improvement of city buses.
