Honda L13 engine troubleshooting and repair
Honda L13AIn 2001, the L13A engine was released, specifically for Honda vehicles of the most modest size. This motor replaced the D13 and D14 series engines. The Honda L13 joined the L series, which also includes the 1.2-liter L12 and the 1.5-liter L15.
The cylinder block of this motor is aluminum with thin liners. It is a long stroke motor with 80 mm crankshaft while the cylinder bore is just 73 mm. Its displacement is only 1.33 liters, which is quite normal for small cars.
The cylinder block was covered with a variety of heads: 8-valve SOHC i-DSI, 16-valve i-VTEC, 16-valve DOHC. Descriptions of all of these versions can be found below, where there is also data on the hybrid 1.33-liter engines.
The L13A uses a timing chain, quite reliable, which usually does not cause problems.
L13A engines have valve adjustments every 45k miles. Clearances on a cold engine: intake 0.15-0.19 mm, exhaust 0.26-0.3 mm.
Modifications of Honda L13 engine
- L13A i-DSI – engine with dual ignition, 2 plugs for each cylinder and with 8 ignition coils. It was designed to reduce fuel consumption, increase low-end torque and improve environmental performance. SOHC 8 valve cylinder head, 10.8 compression ratio, 86 hp at 5700 rpm, 119 Nm of torque at 2800 rpm. The motor was used in Honda Civic 7 and 8, City, Fit and Jazz.
- L13A i-VTEC – SOHC 16 valve head motor with a compression ratio of 10.5, 99 hp at 6000 rpm, and 127 Nm of torque at 4800 rpm. It is found in the Honda Fit and Civic.
- L13B – DOHC 16-valve twin-shaft head engine. The compression ratio has been increased to 13.5 and the engine runs on the Atkinson cycle. Its output reaches 99 hp at 6000 rpm and torque of 127 Nm at 4800 rpm.
- LDA is the motor for the 7th generation Civic Hybrid and 2nd generation Insight. It is an 8-valve single-shaft L13A i-DSI with i-VTEC system that can deactivate 3 cylinders during braking. This engine works in conjunction with an electric motor with 13 hp, which gives extra torque at the lows. Power output of the LDA engine is 98 hp at 5800 rpm, torque is 157 Nm at 1500 rpm.
- LDA2 is the engine for the 8th generation Honda Civic Hybrid. The gasoline engine has been further refined and gets a 3-speed i-VTEC, resulting in 95 hp at 6,000 rpm. There is also an i-DSI and VCM system, the latter can shut down all 4 cylinders, leaving only the electric motor. The electric motor itself has been improved, its power has been increased to 20 hp. In total, this gives 115 hp at 6000 rpm and 167 Nm of torque at 2500 rpm.
Honda L13 engine problems and disadvantages
The motor is quite reliable and has no weak points. It is necessary to change all the plugs, not just four, as it is done. And so everything is standard: timely maintenance and the use of quality working fluids, will help to extend the resource and allow you to drive without problems.
Honda L13A engine tuning
Atmospheric
Tuning such a small motor makes no sense, because it is much easier to change the car to a faster one or buy a contract K20A and put it. You can go the way described in this article, but you will always be behind a similar L15A.
