- a two-stroke diesel engine is started, for example, in such a way that one Cylinder whose piston is immediately after top dead center the outlet valve is closed and compressed air is blown in around the To move the piston towards bottom dead center.
- the exhaust valves of the the remaining cylinders remain open so that they are not essential Compression is generated.
- the exhaust valve is opened again so that the Pistons essentially return to top dead center without compression moved there.
- two cylinders can be used as described Compressed air can be applied to start the diesel engine during the other cylinders are kept essentially compression-free. It However, all cylinders can also be operated with compressed air as described be charged. Because the cylinder at the time the piston located at top dead center, is essentially compression-free prove to be an essential advantage of the method according to the invention The fact that a relatively low air pressure is enough to close the diesel engine start.
- the air used for starting had to be pressurized which was significantly higher than the compression pressure, which rests in the cylinder when starting, when the piston is in the upper one Dead center is located.
- the method according to the invention thus has the advantage that the pressure in the compressed air reservoir can be kept lower, or that the volume of the compressed air reservoir can be kept smaller.
- the Compressed air reservoir advantageously designed with pressure bottles, can thus be made cheaper or smaller, or it can be done with the Content of existing compressed air storage an increased number of starts carry out. In addition, cheaper compressors are available for charging the Compressed air storage can be used.
- the method according to the invention is also suitable for the diesel engine to change, in a first step like this is decelerated to a standstill, being in a second Partial step the compressed air depending on the piston position blown and the exhaust valves are controlled so that the Diesel engine is rotated in the opposite direction, so that in a third Partial step of the diesel engine rotating in the opposite direction with the one already described procedure is started.

- the piston moves to bottom dead center UTP the cylinder pressure 20 decreases and first, as with curve 22 shown, the outlet valve 4a opens, and then, as with the curve 21 shown, the inlet slot of the two-stroke diesel engine is open.
- the inlet slot is closed first, then the Exhaust valve 4a closed, up the cylinder pressure 20 through the compression increases.
- FIG. 2b shows the cylinder pressure 20 as a function of the crank angle ⁇ at starting method according to the invention.
- the exhaust valve 4a is during the Curve 22 opened, curve 22 opening exhaust valve 4a Flank 22a and a flank 22b closing the outlet valve 4a having.
- the exhaust valve 4a In the normal operating state, i.e. during the operation of the Two-stroke diesel engine with constant speed, the exhaust valve 4a in essentially corresponding to the curve 22 shown in FIG. 2a opened and closed.
- the device according to the invention has the Property on that the exhaust valve 4a, as by the flanks 22a, 22b shown, opened and closed at freely selectable crank angles ⁇ can be.
- the inlet slot is in the courses according to Fig.
- the area 24a shows the pressure increase in the cylinder, based on which of the pistons one expanding movement.
- the outlet valve 4a is over the Control curve 22 and the compressed air valve 4b via the control curve 23 controlled so mutually coordinated that the cylinder at about top dead center OTP is essentially compression-free or one has low internal pressure, and that the subsequent injection of Compressed air an increased pressure change in the cylinder or one causes relatively high pressure change in the cylinder.
- the known method according to FIG. 2a is in the method according to FIG. 2b Compressed air with a much lower pressure is required, this Compressed air also causes an increased pressure change in the cylinder, which assists in expanding the piston. Otherwise the start goes like in the description of Fig. 2a already described by after Exceeding a specifiable nominal speed of the diesel engine in the Operating state of an internal combustion engine is transferred.
- the exhaust valve 4a is in a range between -180 degrees and 0 degrees before top dead center OTP, especially in a range between -90 Degrees and 0 degrees before top dead center OTP closed.
- Fig. 2c explains the cylinder pressure 20 as a function of the crank angle represents ⁇ .
- the compression stroke becomes the cylinder, as shown by curve 23, Compressed air supplied so that the pressure is above the pressure otherwise present 20a rises to the cylinder pressure 20, resulting in an area 24a increased cylinder pressure results.
