Consider the following statements:  
1. Recycling exhaust gases with intake increases emission of oxides ofnitrogen from the engine.
2. When the carburettor throttle is suddenly opened, the fuel air mixtureleans out temporarily causing engine stall.
3. The effect of increase in altitude on carburettor is to enrich the entirepart-throttle operation.
4. Use of multiple venturi system makes it possible to obtain a high velocityair stream when the fuel is introduced at the main venturi throat.

Explanation:

Statement 2: When the carburettor throttle is suddenly opened, the fuel air mixture leans out temporarily causing engine stall.
- This statement is correct because when the throttle is suddenly opened, the air rushing into the carburettor may temporarily disrupt the fuel-air mixture, causing it to lean out. This can lead to a temporary engine stall.

Statement 3: The effect of increase in altitude on carburettor is to enrich the entire part-throttle operation.
- This statement is also correct because at higher altitudes, the air density decreases, leading to a decrease in the amount of oxygen available for combustion. To compensate for this, the carburettor needs to enrich the fuel-air mixture to maintain proper combustion. This enrichment is required across all throttle positions, including part-throttle operation.
Therefore, the correct statements are 2 and 3.
