Characteristic Performance of TBD226B Bus Engine

Modular structure is adopted in the design of 226B series diesel engine. As a result, the 226B engine excels at its compact structure and small volume which makes it convenienient for operation and maintenance. Further more, the good changeability of single cylinder head, high extent of universality, standardization and seriation of spare parts make the maintenance more convenient and the running costs lower.

Super power

TBD226B series diesel engine has three types (3-cylinder, 4-cylinder and 6-cylinder). The output power is 70-176kW with torque back up reaching 30%. It can meet the power and torque requirements of different buses.

Reliable quality

226B series diesel engine is manufactured according to 226B design drawings, the materials for main components meet the German standards, and the introduced technique and advanced management method ensure the product quality to catch up with the advanced international level. The first overhaul period is up to 10000 hours.

Good economy

Combustion system is optimized by adopting port shrink combustion chamber, low whirling cylinder head, low flow resistance aspiration system and turbocharger with by-pass valve. By using P7100 injection pump and P injector, the fuel is injected into cylinders with high pressure, the fuel consumption is 20% lower than other engines with same power.

Outstanding performance

With good low temperature startability, the diesel engine can be started normally at -15 centigrade without any assistant device and be started smoothly at -40 centigrade with assistant starting device.Advanced K series turbocharger extends high-efficiency working range of diesel engine, and the engine can work normally on Plateau at an altitude of 3000m.

Low noise

Moving parts of 226B diesel engine with uniform mass, equipped with vibration damper on the front end, and good dynamic balance features are stable in operation. The vibration of the engine is decreased. The noise is 4-5dB lower than that of similar diesel engine. The emission data superiors to Euro II and approaches to Euro III standard.
