What are the causes of insufficient fuel supply in diesel engines?

Reasons for insufficient fuel supply in diesel engines: 1. Clogged fuel filter. Caused by dirty fuel or low fuel freezing point forming ice blockage in winter. 2. Insufficient fuel transfer pump pressure. This fault can be caused by damaged fuel transfer pump, air in fuel lines, wear of fuel pump transmission parts, or damaged diaphragm in diaphragm-type fuel pumps. 3. Insufficient fuel injector opening pressure. Excessive needle valve spring tension, insufficient fuel injection pump output pressure, or leakage in high-pressure fuel lines and connectors can all make the injector needle valve difficult to open. 4. Poor sealing of the delivery valve. 5. Inconsistent fuel supply angle among cylinders. 6. Overly delayed fuel injection timing. 7. Low fuel quality.

What is the difference between a subcompact SUV and a compact SUV?

The differences between a subcompact SUV and a compact SUV are as follows: 1. Appearance: The most intuitive difference is that a compact SUV looks larger than a subcompact SUV, and the actual body size difference is very significant. For example, comparing the Honda CR-V (compact SUV) and the Honda Vezel (subcompact SUV), the Honda CR-V has dimensions of 4585mm/1855mm/1679mm with a wheelbase of 2660mm, while the Honda Vezel has dimensions of 4294mm/1772mm/1605mm with a wheelbase of 2610mm. 2. Practical use: Subcompact SUVs are more suitable for young consumers (before marriage) as personal transportation tools, as they are not ideal for family use due to relatively cramped interior space. On the other hand, compact SUVs are more suitable for family use (after marriage), offering larger interior space that can comfortably accommodate the driving and riding needs of a family of five.
