Common characteristics: The DH10A-series is largely
based on the earlier THD104 engine. Characteristics:
Horizontal design, turbocompressor feed, 9.6 liter dis-
placement. Single circuit coolant-intercooler, separated
from the ordinary coolant system. Lube system with
two full-flow filters and piston cooling from oil sprayed
onto the pistons from underneath. Piston peaks have
been changed but still build on the re-entry model, that
is, a more favourable air rotation and thereby a more
complete combustion. The injection system is electron-
ically controlled (EDC). Injection pressure has been
raised as a result of changes in the injection pump.
Other nozzles also contribute to better combustion, re-
sulting in lower emissions and lower fuel consumption.
Net output has been measured in accordance with ISO 1585 and SAE J 1349. Smoke requirements met according to ECE/
EEC and the Swedish regulations. DH10A fulfils smoke requirements as per 91/542/EEC, Level B (Euro 2) (EC96).
180 kW.
Low emissions for city buses. Wastegate and water-cooled turbo for
flatter torque curve.
210 kW. Low emissions engine for city buses, e.g., articulated buses,
bogie buses. Wastegate and water-cooled turbo for flatter torque
curve.
250 kW.
Engine for Japan. Low Nox-value as per Japanese requirements.

High-output engine for tourist coaches and long-distance buses.
Large number produced. Injection pump has a timer that is electroni-
cally controlled. Saves fuel at high power output.
