Public Bus Engine Breaks Down After 3 Years, Leading to Vehicle Scrapping

In this video, we explore the story of a public bus engine that was repaired 3 years ago but recently broke down, resulting in the entire bus being scrapped. The engine, an MMZ D-245 produced by Minsk Automobile Plant, had a power output of 245 horsepower. The bus, a PAZ4234 high-floor medium-sized bus manufactured by Pavlovsk Bus Factory, underwent modernization around 2007, possibly upgrading the engine to meet Euro 3 standards. The engine's specific emission standards are challenging to trace, but it likely had a 9.2L displacement. The video takes viewers through the engine's disassembly process, revealing significant carbon buildup, oil leaks, and water ingress, indicating improper storage. Despite the engine's age, it remains popular in extremely cold regions due to its operating range of -45°C to 45°C. The video concludes with the engine being refurbished for resale, as the damage was limited to a broken crankshaft, which can be replaced with readily available parts.
