____________________________________________________________________________________
The Yanmar TS190R is a horizontal,
single-cylinder, water-cooled diesel engine representing the most
powerful model in the legendary TS series. This engine is designed for
heavy-duty industrial and agricultural applications requiring reliable
stationary power. The "R" designation indicates a radiator-cooled
version, distinguishing it from hopper-cooled variants.
The Yanmar TS190R employs an indirect injection combustion system with a
pre-combustion chamber, reducing operational noise and allowing stable
operation across varying fuel qualities. With a large 110 mm bore
producing substantial low-end torque, this engine is suited for
demanding tasks including rice hullers, large irrigation pumps, and
agricultural processing equipment. The heavy cast-iron construction and
reinforced crankshaft provide structural integrity for sustained 19
horsepower operation.
The Yanmar TS190R follows a horizontal single-cylinder architecture with
a large bore relative to stroke, optimizing torque production at lower
engine speeds for stationary power applications.

The cylinder block is constructed from heavy cast iron with a horizontal
orientation. The single-cylinder design features a large 110 mm bore
with a parent bore configuration, eliminating replaceable liners. The
block incorporates reinforced main bearing bulkheads supporting a forged
steel crankshaft.
The horizontal cylinder axis reduces overall height, permitting
installation in compact engine compartments. Water jacket passages
surround the upper portion of the cylinder bore for effective heat
dissipation. The crankcase section includes a sump mounting flange for
the oil pan.
The cylinder head is a single-piece cast iron unit mounted on the
cylinder block. The overhead valve arrangement uses pushrods and rocker
arms actuated by a camshaft mounted within the cylinder block. The
engine features two valves per cylinder: one intake and one exhaust.
The indirect injection combustion chamber incorporates a swirl
pre-chamber or pre-combustion chamber where fuel mixes with swirling air
before ignition propagates into the main chamber. Valve seats are
pressed-in inserts of heat-resistant alloy. Valve guides are cast iron
components pressed into the head and reamed to final diameter. Valve
Clearance (cold): 0.20-0.25 mm (0.008-0.010 in) for intake and exhaust.
The TS190R uses a direct injection fuel system. The mechanical in-line
injection pump is gear-driven from the crankshaft. A single
high-pressure line routes fuel from the pump to the injection nozzle
mounted in the cylinder head, producing a finely atomized spray pattern.
A mechanical fuel feed pump transfers fuel from the tank through a
replaceable filter with sediment bowl. The governor is integrated into
the injection pump housing, providing speed regulation for
constant-speed industrial applications.
Injection Timing: 12-14° BTDC
Recommended Fuel: Diesel fuel meeting ASTM D975 or equivalent
Fuel Tank Capacity: 13.7-17.5 L (3.6-4.6 gal) depending on configuration
The lubrication system is a pressurized wet-sump configuration using a
trochoid-type oil pump. This self-priming internal gear pump provides
forced lubrication to all bearing surfaces. Oil is drawn through a wire
mesh strainer from the sump and routed through the main oil gallery.
The gallery distributes oil to the main bearing, connecting rod bearing,
camshaft bearing, and rocker shaft assembly. A pressure relief valve
maintains system pressure within specified limits. The oil pan is
constructed from stamped steel with a drain plug at the lowest point.
Total Oil Capacity: 3.6-4.1 L (3.8-4.3 qt)
Oil Pressure at Rated Speed: 200-300 kPa (29-44 psi)
Recommended Oil Grade: SAE 40 meeting API Class CC or CD
Oil Pressure at Idle (minimum): 70 kPa (10 psi)
The cooling system is a water-cooled configuration with a radiator
(R-type). A belt-driven centrifugal water pump circulates coolant
through the cylinder block and cylinder head. The thermostat, rated at
71-82°C (160-180°F), regulates coolant flow to the radiator for engines
equipped with a cooling system. Coolant expansion tank accommodates
thermal volume changes. The radiator with cooling fan provides heat
rejection for continuous operation.

The Yanmar TS190R serves in industrial and agricultural applications
requiring stationary power delivery.
Agricultural Processing: Rice hullers, grain mills, and coffee
processing equipment. The large 19 hp output at 2200 rpm provides
sufficient power for post-harvest processing operations. Also used in
large irrigation pumps for agricultural water supply.
Industrial Power Units: Stationary generator sets, water pumps for
municipal and construction applications, and air compressors. The
horizontal configuration and single-cylinder simplicity suit remote
installations.
Agricultural Equipment: Power source for small agricultural machinery
including threshers and feed grinders where electric grid access is
unavailable.
Pumping Applications: High-capacity water pumps for irrigation,
drainage, and flood control. The low-speed torque at 1600 rpm enables
