MAN SL202
Encyclopedia
The MAN SL202 was a single-decker bus
built by MAN Nutzfahrzeuge from the mid-1980s, through to 1995, mainly used in Australia
, Germany
and New Zealand
. Much of the design was used in the American version of the SL202, the MAN Americana SL40-102.
The SL202 came with a wide choice of transmissions
, from three- and four-speed Renk
Doromat automatic transmission
s, to three- and four-speed Voith DIWA transmissions, to four- and five-speed ZF Ecomat
5HP500 transmissions. One to date has been retro-fitted with an Allison
World Series B300R4 transmission, creating a largely noticeable increase in performance against similar examples with the three-speed Voith DIWA transmission.
The internal combustion engine
s used in the SL202 were replaced around 1990, from older, smaller, 2566 series engines to newer, larger, 2866 series engines. The majority of pre-1990 SL202s have a 155 kW D2566UH engine, developing about 755 newton metres (557 ft·lbf) of torque
at 1,400 rpm. These D2566 engines have a capacity of 11.413 litres (695.9 cu in) and max out at 2,200 rpm. This same engine was used for the SL200 and is similar in design to that of the OM407h engine used in the Mercedes-Benz O305
.
Post-1990 SL202s have the D2866 engine, with higher power and torque figures. These engines have a capacity of 11.967 litres (729.7 cu in) and maximum output at 2,200 rpm, the design is similar to the OM447h engine of the Mercedes-Benz O405.
The SL202 was replaced by the MAN NL202

Single-decker bus
A single-decker bus or single-decker is a bus that has a single deck for passengers. Normally the use of the term single-decker refers to a standard two-axled rigid bus, in direct contrast to the use of the term double-decker bus, which is essentially a single decked bus with an extra deck and...

The internal combustion engine
Internal combustion engine
The internal combustion engine is an engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber. In an internal combustion engine, the expansion of the high-temperature and high -pressure gases produced by combustion apply direct force to some component of the engine...
