现代柴油机制造厂家一直在寻求提高原发动机的输出功率，降低其排气污染和确保其高可靠性地运转的途径。能够提供高增压压力，皮实、高效的增压器恰好可满足这种要求。为了满足柴油机制造业的需求，ABB公司开发了一种VTR．4P型增压器。它的压比超过了以前的ABB涡轮增压器，而且，可为多方面的用户提供高的成本效益。同时，可保证其有更好的运行可靠性。虽然压比更高了，但效率仍被保持在高的水平，这使得VTR．．4P增压器闻名遐迩。
Modern diesel manufacturers have been looking for ways to increase the output power of the original engine, reduce its exhaust pollution and ensure its high reliability. To provide high supercharging pressure, skin-filled, efficient supercharger just to meet this requirement. In order to meet the needs of the diesel engine manufacturing industry, ABB has developed a VTR. 4P supercharger. Its pressure ratio surpasses the previous ABB turbochargers and offers high cost-effectiveness for a wide range of users. At the same time, to ensure that it has better operational reliability. Although the pressure ratio is higher, but the efficiency is still maintained at a high level, which makes the VTR. . 4P supercharger famous.
